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).

If I may recommend it, give Symfonium a try for an app front end. It’s actually stellar. I tried Finamp with the same and wasn’t as jazzed

I use it, mostly because I wanted to build an analogue to Google Drive/Photos, though it took some work to get it to a point where it felt good. Since the default Photos app feels pretty garbage to me, I installed the Memories app (same thing but better, very like Google photos) as well as Preview Generator & Recognize.

These seem to do the trick. The automated tagging isn’t without its issues (pretty janky, frankly), but I’m pretty content with it to the point where I’m not looking to change in a hurry. Haven’t tried Immich, though it looks pretty enough like I’d probably just go with it since it does the one task it’s supposed to do, but again, I’m comfy and don’t feel the need to find a new home for my photos yet.
