I’d provide a plug for LMS! If you don’t give much of a damn for music video type stuff, it’s pretty solid and exposes more metadata through the Subsonic API than Navidrome does. My use case required Composer tags in addition to the usual smorgasbord. Bonus is that it combines SUPER well with Symfonium and is compatible with Audiomuse AI.

All that said, I would switch over to Jellyfin for music if they upped their music metadata game and made genre exploration a bit easier (assuming you have hundreds of distinct genre tags like I do).

I use Redshift right now and I would LOVE to have something nice and flexible like that. Come to think of it, some halfway reliable documentation would be nice too.
