I know there’s many questions about self hosted Spotify alternatives, but this one has a slight twist.

Does there exist a service or service stack that provides a single sign on web interface where friends/family can login to search for and download music, stream, and create playlists/share playlists (or even their entire library) with other users?

I’ve always used Spotify to an extent as a social network. Almost all playlists are shared with close friends, and we share essentially a unified library. I’d like to replicate this outside of Spotify.

Essentially what Immich does but for music, podcasts, and audio books.

Some type of iPhone & android compatible app would be necessary as well.

The ability to easily upload purchased music from bandcamp as well as download pirated music from something like soulseek would be needed too.
