mulcaheyCross-platform Spotify alternatives?
There's an app called BlackHole, but the music library it provides is very small and oriented in music from India.
HSLThe problem is that music isn't generally FOSS - people would like to be paid for their work. So the next best thing is to set up your own music service where you can add your own music.
Here's a good discussion: https://www.reddit.com/r/selfhosted/comments/rdxbxp/is_there_any_spotifylike_selfhosted_music/
KrustyFOSS doesn't mean that you can't be paid for it...
That's true. However, FOSS usually means that it's free (F) and open-source (OS). Music isn't usually open source - they don't usually share the sheet music or allow free editing/covering/forking of the music. So the worlds don't completely mesh. You can look at a FOSS solution for managing music, but you won't find a ton of FOSS music.

Please don't use direct links to reddit.
There is the fediverse music platform alternative called funkwhale, although it is closer to soundcloud than spotify. https://funkwhale.audio/
