I recently started using Navidrome to stream my old music collection and it's been a pleasure. It's also nudged me to actually download the music I've purchased on Bandcamp -- before that option inevitably goes away.

Same here - Navidrome has been a revelation. Simple to run, nice UI, only issue is that browsers can't support gapless playback, but lots of apps out there to help with that.

During the golden age of mp3/flac KDE's Amarok was awesome, later it had a subpar upgrade to 3.x and was forked off as Clementine, and now Clementine is also becoming creaky...

Aren't you confusing Audacity with Amarok?

Thanks - edited

I know you didn't ask, but I recommend the Vinyl app on Android. It also lets you manage your music in a directory, but a bit more streamlined for listening to music IMO.

I would add Roon to this list. I run the server on my Synology at home and it organizes 2TB of music for me. Then I can use Roon ARC on my phone to stream it from anywhere.
