For iTunes based music player there is also rhythmbox which is standalone (no subsonic server needed). It's what i used until i ultimately switched to navidrome + supersonic. I'll check out feishin since that didn't come up in my initial search last year. Ive liked supersonic though. It has a decent, simple UI and you can play albums by clicking on them

Edit: ok feishin seems pretty cool. I might stick with this
