58-65: Missing null-safety check and inconsistent transaction handling.
If
songisnullorsong.getId()returnsnull, this will throw an NPE. Consider adding defensive null checks similar tofindByArtistandfindByAlbum.Same transaction handling inconsistency as
count()- usestry-with-resourcesinstead ofemf.callInTransaction().🛡️ Suggested fix with null-safety
`@Override` public boolean existsByUniqueId(Song song) { - try (var em = emf.createEntityManager()) { - return em.createQuery("select count(s) from Song s where s.id = :songId", Long.class) - .setParameter("songId", song.getId()) - .getSingleResult() > 0; - } + if (song == null || song.getId() == null) { + return false; + } + return emf.callInTransaction(em -> + em.createQuery("select count(s) from Song s where s.id = :songId", Long.class) + .setParameter("songId", song.getId()) + .getSingleResult() > 0); }src/main/java/org/example/repo/ArtistRepositoryImpl.java (1)
34-41: Missing null-safety check.If
artistisnullorartist.getId()returnsnull, this method will throw an NPE. Consider adding a defensive null check for consistency with the null-handling pattern inSongRepositoryImpl.findByArtist().🛡️ Suggested fix with null-safety
`@Override` public boolean existsByUniqueId(Artist artist) { + if (artist == null || artist.getId() == null) { + return false; + } return emf.callInTransaction(em -> em.createQuery("select count(a) from Artist a where a.id = :artistId", Long.class) .setParameter("artistId", artist.getId()) .getSingleResult() > 0 ); }src/main/java/org/example/ItunesPlayList.java (1)
433-459: Database call on every keystroke is inefficient.
filterSongscallspri.findById(currentList).getSongs()on every filter change, hitting the database on each keystroke. The songs are already loaded in the selected playlist object. Consider using the cached data instead.🐛 Suggested fix
private void filterSongs(String searchText) { Playlist selectedPlaylist = sourceList.getSelectionModel().getSelectedItem(); if (selectedPlaylist == null) return; - Long currentList = selectedPlaylist.getId(); - ObservableList<Song> masterData = FXCollections.observableArrayList(pri.findById(currentList).getSongs()); + ObservableList<Song> masterData = FXCollections.observableArrayList(selectedPlaylist.getSongs()); if (searchText == null || searchText.isEmpty()) { songTable.setItems(masterData); return; }

In `@src/main/java/org/example/DatabaseInitializer.java`:
- Around line 33-34: The inline comment in DatabaseInitializer near the
songRepo.count() check has a grammatical error ("artist" should be plural);
update the comment to read something like "Limited amount of artists because the
scope of the project" (or better: "Limited number of artists because of project
scope") so it uses the correct plural and clearer phrasing; locate the comment
adjacent to the if (songRepo.count() == 0) check in the DatabaseInitializer
class and replace the wording accordingly.
🧹 Nitpick comments (11)
src/main/java/org/example/DatabaseInitializer.java (1)
72-72: Consider standardizing comment language for consistency.The comments mix Swedish and English. For improved maintainability and broader team accessibility, consider using English consistently throughout the codebase.
Also applies to: 77-77
src/main/java/org/example/entity/Song.java (1)
43-48: Minor: Non-standard grammar in error message."Cannot" is the standard single-word form; "can not" as two words is grammatically non-standard. However, this appears to be an intentional repo-wide consistency choice based on similar changes in
Album.javaandArtist.java.src/main/java/org/example/repo/SongRepositoryImpl.java (1)
44-50: Inconsistent transaction handling pattern.This method uses
try-with-resourcesdirectly on the EntityManager, while other methods in this class useemf.callInTransaction()oremf.runInTransaction(). Consider aligning with the transactional pattern for consistency.♻️ Suggested refactor for consistency
`@Override` public Long count() { - try (var em = emf.createEntityManager()) { - return em.createQuery("select count(s) from Song s", Long.class) - .getSingleResult(); - } + return emf.callInTransaction(em -> + em.createQuery("select count(s) from Song s", Long.class) + .getSingleResult()); }src/main/java/org/example/MyPod.java (1)
768-782: Unused local variableemf.The
emfvariable is assigned but never used in this method. TheDatabaseInitializerand repositories already have their ownEntityManagerFactoryreferences.♻️ Suggested fix
private void initializeData() { try { - EntityManagerFactory emf = PersistenceManager.getEntityManagerFactory(); DatabaseInitializer initializer = new DatabaseInitializer(apiClient, songRepo, albumRepo, artistRepo, playlistRepo); initializer.init(); // Fyll databasen om den är tomsrc/main/java/org/example/repo/AlbumRepositoryImpl.java (3)
40-47: Consider adding null validation for consistency.Unlike
PlaylistRepositoryImplwhich validates inputs and throwsIllegalArgumentExceptionwith logging, this method accepts the album without null checks. Ifalbumoralbum.getId()is null, this could cause unexpected behavior or cryptic JPA errors.♻️ Suggested improvement
`@Override` public boolean existsByUniqueId(Album album) { + if (album == null || album.getId() == null) { + throw new IllegalArgumentException("Album and album id can not be null"); + } return emf.callInTransaction(em -> em.createQuery("select count(a) from Album a where a.id = :albumId", Long.class) .setParameter("albumId", album.getId()) .getSingleResult() > 0 ); }
66-69: Missing null validation.The
savemethod should validate thatalbumis not null before persisting, consistent with the validation pattern inPlaylistRepositoryImpl.♻️ Suggested improvement
`@Override` public void save(Album album) { + if (album == null) { + throw new IllegalArgumentException("Album can not be null"); + } emf.runInTransaction(em -> em.persist(album)); }
89-96: Missing null validation on artist parameter.For consistency with
PlaylistRepositoryImpl, consider adding null validation.♻️ Suggested improvement
`@Override` public List<Album> findByArtist(Artist artist) { + if (artist == null) { + throw new IllegalArgumentException("Artist can not be null"); + } return emf.callInTransaction(em -> em.createQuery("select a from Album a where a.artist = :artist", Album.class) .setParameter("artist", artist) .getResultList() ); }src/main/java/org/example/repo/PlaylistRepositoryImpl.java (2)
53-53: Minor: "can not" vs "cannot".Standard English uses "cannot" as one word. This appears throughout the file (lines 53, 97, 129, 149, 171, 189, 211, 230, 260, 292). Consider using "cannot" for consistency with common conventions.
126-135: Consider usingfind()instead ofmerge()for read operations.Using
merge()could unintentionally persist modifications if the detachedplaylistobject has been changed. For a pure read operation,em.find(Playlist.class, playlist.getId())would be safer.♻️ Suggested improvement
`@Override` public Set<Song> findSongsInPlaylist(Playlist playlist) { if (playlist == null) { logger.error("findSongsInPlaylist: playlist is null"); throw new IllegalArgumentException("playlist can not be null"); } return emf.callInTransaction(em -> { - Playlist managed = em.merge(playlist); + Playlist managed = em.find(Playlist.class, playlist.getId()); + if (managed == null) { + throw new IllegalArgumentException("Playlist not found with id: " + playlist.getId()); + } return managed.getSongs(); }); }src/main/java/org/example/ItunesPlayList.java (2)
384-412: Consider extracting magic numbers to named constants.The hardcoded IDs
1Land2Lfor Library and Favorites playlists appear multiple times throughout the file (lines 386, 411, 489, 522, 541, 561). Extracting these to named constants would improve readability and maintainability.♻️ Suggested improvement
private static final Long LIBRARY_PLAYLIST_ID = 1L; private static final Long FAVORITES_PLAYLIST_ID = 2L;Then use these constants instead of the magic numbers throughout the code.
110-114: Consider adding error handling for async loading.The async loading is a good pattern, but if
pri.findAll()throws an exception, it will be silently swallowed. Consider wrapping in try-catch with appropriate user feedback.♻️ Suggested improvement
// Load playlists asynchronously to avoid blocking the JavaFX thread new Thread(() -> { - List<Playlist> pls = pri.findAll(); - javafx.application.Platform.runLater(() -> allPlaylistList.setAll(pls)); + try { + List<Playlist> pls = pri.findAll(); + javafx.application.Platform.runLater(() -> allPlaylistList.setAll(pls)); + } catch (Exception e) { + logger.error("showLibrary: Failed to load playlists", e); + javafx.application.Platform.runLater(() -> + new Alert(Alert.AlertType.ERROR, "Failed to load playlists").showAndWait() + ); + } }).start();

39-44: Consistent with other entity classes.Same grammatical note as
Song.javaapplies here. The change maintains consistency across entity classes.src/main/java/org/example/entity/Album.java (2)
58-67: Good documentation clarification.The updated comment on line 63 clearly documents the fallback behavior for album cover loading, which helps maintainers understand the expected UI handling.
145-158: LGTM - JavaDoc improvements.The JavaDoc additions for
generateAlbumCoverandimageToBytesproperly document the null-return behavior, improving API clarity.src/main/java/org/example/repo/SongRepositoryImpl.java (3)
13-25: LGTM - Good class-level documentation.The JavaDoc clearly explains the repository's purpose and the eager fetching strategy to avoid lazy loading issues.
89-119: Good null-safety and eager fetching implementation.The null check with debug logging and the eager fetch of album/artist associations are well implemented. Returning an empty
ArrayListfor null input is a sensible defensive approach.
121-147: LGTM - Consistent with findByArtist pattern.The implementation mirrors the null-safety and eager fetching pattern from
findByArtist, maintaining consistency.src/main/java/org/example/repo/ArtistRepositoryImpl.java (2)
8-15: LGTM - Good class-level documentation.Clear and concise JavaDoc explaining the repository's purpose and capabilities.
48-75: LGTM - Clean CRUD implementations.The
count(),save(), andfindAll()methods are well-implemented with consistent transactional patterns and proper JavaDoc.src/main/java/org/example/MyPod.java (2)
638-714: Cleaner approach using the Song entity directly.The refactored
showNowPlayingmethod is a good improvement. It directly casts the selection object toSonginstead of performing an in-memory search, which is more efficient and cleaner. The null check on line 638-639 properly guards against NPE before the cast.
59-86: Documentation comments look good.The added Swedish comments help explain the code structure. The formatting changes are clean.
src/main/java/org/example/repo/AlbumRepositoryImpl.java (1)
9-21: Good Javadoc documentation.The class-level and method-level Javadoc is well-written and follows standard conventions.
src/main/java/org/example/repo/PlaylistRepositoryImpl.java (3)
15-28: Excellent Javadoc documentation.The comprehensive class-level and method-level documentation clearly explains the repository's responsibilities and transactional behavior.
146-158: Looks good.The null checks and playlist existence handling are appropriate. Returning
falsewhen the playlist doesn't exist is a reasonable semantic choice.
167-279: Solid implementation with consistent patterns.The CRUD and relationship management methods follow consistent patterns with proper null validation, transaction handling, and error logging.
src/main/java/org/example/ItunesPlayList.java (2)
42-68: Good dependency injection and callback pattern.The constructor properly accepts
PlaylistRepositoryfor dependency injection, and thesetOnUpdate/refreshmechanism provides a clean way to notify external components of state changes.
306-344: Good defensive programming in table setup.The cell value factories properly handle null cases for song, album, and artist fields, providing sensible defaults like "Unknown title", "Unknown artist", etc.

In `@src/main/java/org/example/DatabaseInitializer.java`:
- Around line 106-113: Replace fragile ID-based existence checks in
DatabaseInitializer with a name-based check: add boolean existsByName(String
name) to PlaylistRepository and implement it in PlaylistRepositoryImpl (validate
name, query Playlist by name and return whether count>0). Then update
DatabaseInitializer to call playlistRepo.existsByName("Library") and
playlistRepo.existsByName("Favorites") before creating those playlists and
adding songs, removing the hardcoded 1L/2L checks.
In `@src/main/java/org/example/ItunesPlayList.java`:
- Around line 206-221: The call to sourceList.getSelectionModel().selectFirst()
may run before playlists finish loading; move the selectFirst() call into the
Platform.runLater block that sets allPlaylistList (after calling setAll(pls)) so
it runs on the FX thread after data is populated, and only invoke selectFirst()
if the list is non-empty (e.g., check !allPlaylistList.isEmpty() or
sourceList.getItems().isEmpty() before calling selectFirst()).
🧹 Nitpick comments (10)
src/main/java/org/example/EntityManagerFactoryProvider.java (1)
39-57: Consider null-safety forextraPropsparameter.If
extraPropsis passed asnull, line 54 will throw aNullPointerException. Consider adding a null check or usingMap.of()as default.💡 Suggested null-safe approach
public static EntityManagerFactory create( String jdbcUrl, String username, String password, Map<String, String> extraProps ) { List<Class<?>> entities = scanEntities("org.example.entity"); PersistenceConfiguration cfg = new HibernatePersistenceConfiguration("emf") .jdbcUrl(jdbcUrl) .jdbcUsername(username) .jdbcPassword(password) .managedClasses(entities); - extraProps.forEach(cfg::property); + if (extraProps != null) { + extraProps.forEach(cfg::property); + } return cfg.createEntityManagerFactory(); }src/main/java/org/example/PersistenceManager.java (1)
17-27: Hardcoded database credentials should be externalized.The JDBC URL, username, and password are hardcoded. Consider using environment variables, a configuration file, or a properties file to avoid committing credentials and to support different environments (dev, test, prod).
💡 Example using environment variables
private static final EntityManagerFactory emf = EntityManagerFactoryProvider.create( - "jdbc:mysql://localhost:3306/myPodDB", - "user", - "pass", + System.getenv().getOrDefault("DB_URL", "jdbc:mysql://localhost:3306/myPodDB"), + System.getenv().getOrDefault("DB_USER", "user"), + System.getenv().getOrDefault("DB_PASS", "pass"), Map.of( "hibernate.hbm2ddl.auto", "update", "hibernate.show_sql", "true", "hibernate.format_sql", "true" ) );src/main/java/org/example/ItunesApiClient.java (2)
71-75: Inconsistent language in error message.The exception message uses Swedish ("API-fel") while the rest of the codebase appears to use English. Consider using English for consistency.
💡 Suggested fix
if (response.statusCode() != 200) { logger.error("searchSongs: status code {}", response.statusCode()); - throw new RuntimeException("API-fel: " + response.statusCode()); + throw new RuntimeException("API error: " + response.statusCode()); }
116-123: Consider reducing visibility ofnormalizemethod.The
normalizemethod appears to be an internal helper for artist name comparison. Making it package-private or private would better encapsulate the implementation detail.💡 Suggested change
- public String normalize(String s) { + String normalize(String s) { // package-private for testingsrc/main/java/org/example/ItunesPlayList.java (4)
107-122: Consider naming the background thread for easier debugging.The async loading pattern is correct, but unnamed threads can be harder to diagnose in thread dumps or logs.
♻️ Optional improvement
- new Thread(() -> { + Thread loader = new Thread(() -> { try { List<Playlist> pls = pri.findAll(); javafx.application.Platform.runLater(() -> allPlaylistList.setAll(pls)); } catch (Exception e) { logger.error("showLibrary: Failed to load playlists", e); javafx.application.Platform.runLater(() -> new Alert(Alert.AlertType.ERROR, "Failed to load playlists").showAndWait() ); } - }).start(); + }); + loader.setName("PlaylistLoader"); + loader.setDaemon(true); + loader.start();
391-419: Consider handling additional exception types beyondIllegalStateException.On Lines 402-405, only
IllegalStateExceptionis caught. Repository methods throwIllegalArgumentExceptionfor validation failures. Catching a broader exception type (or both) would ensure all error cases show the alert.♻️ Suggested fix
- } catch (IllegalStateException ex) { + } catch (RuntimeException ex) { logger.error("setupTable: add song failed", ex); new Alert(Alert.AlertType.ERROR, "Failed to add song: " + ex.getMessage()).showAndWait(); }
519-533: Consider adding error handling fordeletePlaylist.Unlike
renameSelectedPlaylist, this method doesn't wrap the repository call in try-catch. If deletion fails, the user won't see an error message.♻️ Suggested fix
private void deleteSelectedPlaylist() { Playlist sel = sourceList.getSelectionModel().getSelectedItem(); if (sel != null && sel.getId() != null && !sel.getId().equals(1L) && !sel.getId().equals(2L)) { - pri.deletePlaylist(sel); - allPlaylistList.remove(sel); - refresh(); + try { + pri.deletePlaylist(sel); + allPlaylistList.remove(sel); + refresh(); + } catch (RuntimeException ex) { + logger.error("deleteSelectedPlaylist: failed to delete", ex); + new Alert(Alert.AlertType.ERROR, "Failed to delete: " + ex.getMessage()).showAndWait(); + } } }
535-553: Consider adding error handling forremoveSong.Similar to
deleteSelectedPlaylist, this method lacks try-catch around the repository call.♻️ Suggested fix
private void removeSelectedSong() { Song sel = songTable.getSelectionModel().getSelectedItem(); Playlist list = sourceList.getSelectionModel().getSelectedItem(); // You can not remove song from Library if (sel != null && list != null && list.getId() != null && !list.getId().equals(1L)) { - pri.removeSong(list, sel); - list.getSongs().remove(sel); - songTable.getItems().remove(sel); - refresh(); + try { + pri.removeSong(list, sel); + list.getSongs().remove(sel); + songTable.getItems().remove(sel); + refresh(); + } catch (RuntimeException ex) { + logger.error("removeSelectedSong: failed to remove song", ex); + new Alert(Alert.AlertType.ERROR, "Failed to remove song: " + ex.getMessage()).showAndWait(); + } } }src/main/java/org/example/MyPod.java (2)
602-637: Consider naming the background thread for debugging.Similar to
ItunesPlayList, the anonymous thread on Line 615 would benefit from a name for easier debugging.
800-837: MediaPlayer resource cleanup on application exit.The
MediaPlayeris properly disposed when a new preview starts, but if the application closes while playing, the player isn't explicitly stopped. Consider adding cleanup in astop()override.♻️ Suggested addition
`@Override` public void stop() { if (mediaPlayer != null) { mediaPlayer.stop(); mediaPlayer.dispose(); } }

13-22: LGTM! Well-written class documentation.The Javadoc accurately describes the class purpose, programmatic Hibernate configuration, and automatic entity discovery.
68-77: Clean implementation of entity scanning.Good use of try-with-resources for the
ScanResultand proper ClassGraph configuration for annotation scanning.src/main/java/org/example/PersistenceManager.java (2)
7-15: LGTM! Clear documentation of singleton pattern.The Javadoc accurately describes the centralized access pattern and automatic shutdown behavior.
29-31: Good use of shutdown hook for resource cleanup.This ensures the
EntityManagerFactoryis properly closed when the JVM terminates, preventing resource leaks.src/main/java/org/example/ItunesApiClient.java (1)
19-28: LGTM! Comprehensive class documentation.The Javadoc clearly explains the class responsibilities including HTTP request execution, response mapping, and result filtering.
src/main/java/org/example/DatabaseInitializer.java (2)
13-25: LGTM! Thorough class documentation.The Javadoc clearly outlines the responsibilities (API fetching, persistence, default playlist creation) and idempotent behavior.
66-104: Initialization logic is well-structured.Good use of idempotent checks (
existsByUniqueId) before persisting entities, and proper error handling with logging before re-throwing. The transaction scope per search term is appropriate.src/main/java/org/example/ItunesDTO.java (2)
8-29: LGTM! Well-documented DTO record.The Javadoc clearly explains the purpose as an intermediate representation from the iTunes API. Good use of
@JsonIgnoreProperties(ignoreUnknown = true)to handle API response flexibility.
31-38: Clean implementation with proper null handling.The
releaseYear()method correctly handles the null case by returning0, and the Javadoc accurately documents this behavior.src/main/java/org/example/repo/PlaylistRepositoryImpl.java (10)
15-28: LGTM!The class-level JavaDoc is well-structured and accurately describes the repository's responsibilities, transaction handling, and resource management patterns.
42-60: LGTM!The
existsByUniqueIdmethod has clear documentation and appropriate null-id validation with a descriptive error message.
62-82: LGTM!The
findAllmethod documentation correctly explains theDISTINCTusage to prevent duplicates from join fetching. The eager fetch strategy is clearly documented.
84-116: LGTM!The
findByIdmethod has proper null validation, appropriate exception handling convertingNoResultExceptiontoEntityNotFoundException, and complete documentation.
141-157: LGTM!The
createPlaylistmethod correctly validates name, persists within a transaction, and returns the managed entity.
159-180: LGTM!The
renamePlaylistmethod properly validates inputs, re-fetches the entity within the transaction context, and handles the not-found case appropriately.
182-198: LGTM!The
deletePlaylistmethod correctly usesmergeto attach the potentially detached entity before removal.
200-260: LGTM!Both
addSongandaddSongsmethods properly validate inputs, fetch managed entities within the transaction, and handle not-found cases with appropriate error messages.
262-292: LGTM!The
removeSongmethod follows the same consistent pattern as the add methods with proper validation and entity management.
118-139: No issue with entity equality inisSongInPlaylist.
Songoverridesequals()with proper ID-based comparison (line 116 of Song.java:Objects.equals(getId(), song.getId())), so thecontains()call will correctly identify the detachedsongparameter against managed entities frommanaged.getSongs()by comparing their IDs. The method works as intended.Likely an incorrect or invalid review comment.
src/main/java/org/example/ItunesPlayList.java (6)
23-49: LGTM!The class-level JavaDoc and constructor documentation clearly describe the UI's responsibilities and its dependency on
PlaylistRepository.

Add name-based playlist existence check instead of hardcoded IDs.
Using hardcoded IDs (1L, 2L) to check for playlist existence at lines 107 and 111 is fragile and assumes specific auto-increment behavior. If the database is reset or IDs are assigned differently (e.g., in a different order), these checks will fail silently and create duplicate "Library" and "Favorites" playlists.
Implement an existsByName(String name) method in PlaylistRepository and use it instead:

`@Override`
public boolean existsByName(String name) {
if (name == null || name.trim().isEmpty()) {
throw new IllegalArgumentException("name cannot be null or empty");
}

Replace fragile ID-based existence checks in DatabaseInitializer with a
name-based check: add boolean existsByName(String name) to PlaylistRepository
and implement it in PlaylistRepositoryImpl (validate name, query Playlist by
name and return whether count>0). Then update DatabaseInitializer to call
playlistRepo.existsByName("Library") and playlistRepo.existsByName("Favorites")

801-838: Progress binding may leak when navigating away from Now Playing.The
progressBar.progressProperty()is bound at line 815 and only unbound insetOnEndOfMedia(line 830). If the user navigates away mid-playback (e.g., pressing ESC), the binding remains active, potentially causing issues with detached UI elements.Consider unbinding the progress property when leaving the Now Playing screen.
💡 Suggested approach
Add cleanup logic when navigating away from NowPlaying, for example in the ESC handler or when clearing the screen:
private void cleanupMediaPlayer() { if (progressBar != null) { progressBar.progressProperty().unbind(); } if (mediaPlayer != null) { mediaPlayer.stop(); mediaPlayer.dispose(); mediaPlayer = null; } }Then call this method when navigating away from NowPlaying in
setupNavigation.

Early return leaves inconsistent UI state.
If selection.object() is null, the screen is cleared and currentScreenName is set to "NowPlaying", but then the method returns early, leaving an empty screen. The user can still navigate back via ESC, but the state is inconsistent.
Consider either setting currentScreenName after the null check, or displaying a fallback message.

153-171: Consider separating UI concerns from the entity.The method is functionally correct with proper null/error handling. However, placing JavaFX-specific logic (
Image,isError()) in a JPA entity couples the persistence layer to the UI framework, which can complicate testing and violate separation of concerns.Consider moving this conversion logic to a UI helper or service class that transforms the entity's
byte[]into anImage. The entity would remain framework-agnostic.

In `@src/main/java/org/example/ItunesPlayList.java`:
- Around line 528-535: The deleteSelectedPlaylist method lacks error handling
around the pri.deletePlaylist call; wrap the deletion in a try-catch so
exceptions from pri.deletePlaylist(sel) are caught, log or show the error (e.g.,
via logger or a user Alert), and only remove from allPlaylistList and call
refresh() when the delete succeeds; if an exception occurs, do not mutate
allPlaylistList and ensure the UI remains consistent (keep sourceList
selection/state), and include references to deleteSelectedPlaylist,
pri.deletePlaylist(sel), allPlaylistList.remove(sel), and refresh() when
updating the code.
- Around line 544-555: Wrap the body of removeSelectedSong in a try-catch that
catches repository-related failures (e.g., Exception) around the call to
pri.removeSong(list, sel) and the subsequent list/songTable mutations; on catch
log the error (using the class logger or existing logging utility) and display a
user-friendly error/alert so the UI doesn’t silently fail, then avoid calling
refresh on failure. Ensure you reference the existing pri.removeSong,
list.getSongs().remove, songTable.getItems().remove and refresh() calls when
adding the error handling.
- Around line 269-271: The call to
getClass().getResource("/ipod_style.css").toExternalForm() can NPE if the
resource is missing; update the code around scene.getStylesheets().add(...) to
first retrieve URL url = getClass().getResource("/ipod_style.css"), check url !=
null, and only call toExternalForm() and add the stylesheet when non-null
(otherwise log a warning or skip/fall back to a default stylesheet); reference
the getClass().getResource("/ipod_style.css") call and the
scene.getStylesheets().add(...) invocation when making the change.
- Line 356: The call in ItunesPlayList where you set the table
policy—songTable.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY)—uses
a deprecated constant; replace it with the newer policy constant that matches
desired behavior (either TableView.CONSTRAINED_RESIZE_POLICY_FLEX_LAST_COLUMN
for flexible last-column resizing or
TableView.CONSTRAINED_RESIZE_POLICY_ALL_COLUMNS to constrain all columns),
update the argument passed to songTable.setColumnResizePolicy(...) accordingly,
and ensure your build targets the JavaFX version that defines the chosen
constant.

393-396: Consider extracting magic IDs to named constants.The values
1L(Library) and2L(Favorites) appear in multiple places for identifying system playlists. Extracting these to constants would improve readability and reduce the risk of inconsistencies if the IDs ever change.♻️ Example refactor
private static final Long LIBRARY_PLAYLIST_ID = 1L; private static final Long FAVORITES_PLAYLIST_ID = 2L;Then replace usages like:
-if (pl.getId() != null && pl.getId().equals(1L)) continue; +if (pl.getId() != null && pl.getId().equals(LIBRARY_PLAYLIST_ID)) continue;Also applies to: 419-420, 497-498, 529-530, 548-549, 569-570

42-49: LGTM!Constructor properly initializes the repository dependency. Documentation is clear.
111-126: LGTM! Async loading issue properly addressed.The
selectFirst()call is now correctly placed inside thePlatform.runLaterblock aftersetAll(pls), ensuring the selection only occurs after data is loaded. The empty-list guard is a good defensive addition.
315-434: Overall setupTable implementation looks solid.The table configuration, selection handling, and context menu logic are well-structured. The dynamic submenu population correctly excludes the library playlist, and the error handling for add operations is appropriate.
442-467: LGTM!The filter implementation correctly handles null/empty search text and checks all relevant fields (title, artist, album) with proper null guards.

… removeSelectedSong, replace deprecated CONSTRAINED_RESIZE_POLICY with newer alternative

Start add Java Docs, remove unused methods, remove AppIT class, update showNowPlaying to use Song entity instead of filtering.
