Okay, after two evenings debugging weird Music Artist behavior in Jellyfin, I'm open to just replacing it with a differently cursed stack.

What I need:
- Playback on Android and Linux (web client might be sufficient)
- DLNA support (at least via Android)
- MusicBrainz/ListenBrainz
- Offline playback on Android
- Android Auto

All Android boxes are ticked if I can use Symfonium. But if there is a FOSS client that can do it, I'd be not opposed.

Current contestants:
- Navidrome
- Music Assistant

@zhenech I've also been trying to find a better alternative to the Synology "Audio Studio".

I did try both Navidrome and Music Assistant, but honestly, neither is really great.

The Music Assistant web player is wonky. I think it's only useful if you use it to play on remote receivers.

Navidrome is OK, but the library browsing experience is a bit meh, almost as bad as the (default) music browsing in Jellyfin.

I still have Ampache and Roon on my list to try.
