Huh, interesting. I usually have full copies of my music collection where I need them (512gb microsd in my phone and on the work laptop) but it would be nice to just have a web interface if I'm at someone's house or so they can play off their phone. I think I was using subsonic until they changed all their licensing.
One UI question? Is there a reason you left off volume controls? That's something that always annoys me still about Bandcamp and I had submitted a patch to Mastodon to create a volume control for their video component.
