Bug? Multiple stations' music are merged together #32
Description
There seems to be a bug where tracks in multiple stations are merged together if they have the same parent directory name. In my install of CSL for MacOS, I have two stations "A" and "B", each with a subdirectory named "Music". In both stations' JSON files' collections properties, they both have an entry "Music". What I found is that Station A's music list has everything in A/CSLMusicMod_Music/Music, but Station B's list contains both A/CSLMusicMod_Music/Music and also B/CSLMusicMod_Music/Music.
I worked around this by giving unique names to subdirectories (i.e., A/CSLMusicMod_Music/A_Music).
