It’s probably a bit newer than you mean, but I still use Cantata as my music player. Using mpd as the backend has some nice benefits, and I like the UI. I do build it with a patch to tweak the track art handling, though.
The official web client works very well as a PWA on mobile.
The official native apps are also an option, but are controversial for a number of reasons. I don’t use it, but from what I’ve heard Tusky is a very popular alternative.
I believe this is the number displayed if you view the community on the original instance?
