The streaming was easy, just declared I wasn’t paying for it anymore lol. We still have a crappy version of Spotify for free because of another service (ISP or phone plan something like that), but it’s purely used as a backup.

Jellyfin’s interface is a bit clunky as a music client in my experience. FinAmp looks cool but it’s still early on.

Navidrome does smart playlist, crossfading, gapless, flac streaming, and flac to opus transcoding. Those are sorta my core requirements, and Navidrome + the clients we use handles them all with aplomb.

As for the user playlist thing… I haven’t seen anything like that but maybe I’m misunderstanding.
