Apple Music added as fallback metadata source if Spotify is not available. Spotify is always preferred if it is available with its richer data responses. Will easily swap from Spotify to Apple Music on the fly if you are rate limited by Spotify or worse, temp banned.
Apple Music and Spotify will now each have their own discovery pool for the discover page. Both will always be updated on every watchlist scan so long as Spotify is authorized, otherwise only Apple Music data is pulled.
Known issues:
Any artist image pulled while Apple Music is the primary source will only pull album art for that artist since they do not provide artist images :( Since the app uses a random album image as artist photo this can, very rarely, lead to cases where the album image that is pulled could have another another artist displayed if it's some collab single, EP or something. Seen it happen once with an indie artist so it's possible.
Looking for a great api / website to parse easily specifically for artist photos and a huge db to pull from.
