This looks nice! I am really interested in this space because I have a long build collection of mp3s and I'm not as interested in yielding to Spotify but I'm not always at the same computer or building for the accessibility.

Thus far I've been using mStream https://mstream.io/ with decent success. You can federate collections with your friends. My tries with NFS or SSHFS doesn't work reliably on windows/mobile hosts, especially across the (mobile) internet.

I know there is at least a few other projects in this space, some mentioned in the comments (Ampache.)

mStream does look very nice and straightforward. Is there any better UI for seeing all your music than what appears to be just a file dialog?

It's pretty file dialog-y utilitarian but you can have it group by album/artist and also has a unified search through the library. I haven't explored its AutoDJ feature.
