@fmartingr Jellyfin is a good alternative to Plex, but I don't know if it's very good for music (never used it for that).
Take a look at this list: https://github.com/awesome-selfhosted/awesome-selfhosted#audio-streaming
It should have some good stuff in there, notably Funkwhale and Subsonic-compatible servers have good Android apps on F-Droid
@Matter Oh my I always forgot about the awesome-x pages! There must be something to fit my needs in there, thanks!
