- Picard for import/metadata
- Navidrome for a web interface + Subsonic server
- DSub on Android to play (+ permanent cache for offline playback of various "deserted island" albums)
If you have Poweramp (Android), it can read the cache folder of DSub. This is the best audio configuration I've found thus far. It's great. Navidrome is one of the best software packages I've found recently. Love it. Picard is equally amazing once you get the hang of the UI.
