Apple Music Support?
Unsure if possible. I have 0 knowledge on if the Apple Music API/MusicKit provides listening status or anything similar. Bonus if animated art is supported, as an equivalent to Spotify Canvas. Not sure what the equivalent to a Spotify code is. Maybe a regular URL or shortened one, or a QR code? I think MusicKit does provide colours as to prevent visually clashing colours while using the official app/full screen immersive mode as shown by Cider 2:
Hi, after looking at it a bit it seems that Cider is closed source (the actual code is not publicly available and distributed under a license).
MusicKit / AM api is only used to play on demand on the web or to offer music related data but does not allow to read what the user is currently doing so no "now playing" also the apple dev account is paid.
The best way to do this would be to add the player and not the provider (example, a sonos, a denon amp) if you are listening in the native AM client I don't think that it can be done (at least easily)
Where are you paying the music?
I am playing the music from either the official Android client, PS5 client, or Cider2 on Windows/Linux.
There is a ListenBrainz plugin for Cider2. https://marketplace.cider.sh/plugins/10 This might be the better solution than just AM, as it could provide support for all sorts of players/configurations.
https://covers.musichoarders.xyz/ and this site provides album covers, including the animated ones from AM. Not sure if they have a public API but theres a page called integrations.
covers.musichoarders.xyz is great, will use it for other projects.
About AM or similar I will merge any PR that add support for it (or any similar sonos, heos, etc), but Im not going to add this changes as I do not use the service.
I will keep this issue open for any want that wants to contribute. Thanks
