**IMPORTANT**
Please note that the API key I received from ACRCloud for song identification will expire on **3/24**, so the app may not work properly after this time. 

To run the app's client, run the python file, which will be able to connect to the server and work properly.
To setup the app's server - 
You will need to configure the following AWS resources:

1. **S3 Bucket**
   - Name: `photoapp-max-nu-cs310`
   - Used for storing uploaded audio files.
   - Files go into the `uploads/` folder.

2. **RDS (MySQL) Database**
   - Use the provided `tunefinder sql.sql` to create:
     - `jobs` table (stores uploaded file metadata)
     - `songs` table (stores song results)
     - Create users `tunefinder-read-only` and `tunefinder-read-write`

3. **Lambda Functions**
   - Set up the three lambda functions - tunefinder_upload, tunefinder_songs, and tunefinder_identify, with the included files and config
   - Add environment variables to tunefinder_identify function:
     - `API_HOST`, `API_ACCESS_KEY`, `API_SECRET_KEY` (for ACRCloud)

4. **Layers**
   - Add a layer for FFmpeg binaries, MySQL, as well as requests and cryptography for RDS access

5. **API Gateway**
   - Create REST API with routes:
     - `POST /upload` - triggers `tunefinder_upload`
     - `POST /identify` - triggers `tunefinder_identify`
     - `GET /songs` - triggers `tunefinder_songs`
   - Enable Lambda proxy integration
   - Make sure IAM permissions allow `apigateway.amazonaws.com` to invoke functions, I created policies for each of the functions

Run the client:
   python3 main.py
