Plex has a dedicated music app now. The latest update fixed most of the issues I had and it’s become my main music player. It requires a Plex Pass but I got the lifetime pass years ago.
It does a great job organizing my library, adding art and descriptions. It had issues with some multi-disc collections but there are editing tools to fix those.
It’s nice to be able to choose between the various versions of albums I have, including bootlegs. It will play FLAC files if you have them.
