The Issue: Using file names as playlist names fails in cases where the playlist names include characters encoded in sets that are not suported by the FAT file system, especially foreign language scripts.
A Solution: Use an internal list of objects to track synced playlists.
Maybe even just seralize PlaylistInfo.
Considerations: File based sytem is elegant, so it'd be nice to handle cases where the playlist file is deleted or one is added to the file system by the user.
