I loved the idea of navidrome and also briefly ran an instance, and like you use plexamp heavily. I stopped using Navi because one day it broke, and I found the plexamp experience just better.

Maybe it’s time to try again.

Jellyfin is actually open source and free. Totally self hosted. Emby is closed source and has a licensing model similar to Plex’s.
