I really like my music setup right now:
- first I purchase music as mp3 (amazon, google play, bandcamp, etc)
- then I sync it to phone, media server, backup server and even to car radio using syncthing (screenshot 1)
- I can play it on my PC using Lollypop and control playback from my phone using KDE Connect (screenshot 2) and because it's synchronized with my phone and car I can play it offline no problem using native apps (LineageOS "Eleven" here, screenshot 3)
everything #foss and DRM-free!
now all that is missing is playlist synchronization from Lollypop (which already supports it over USB) via wifi with syncthing, probably requiring a separate app to import as android standard music playlists and exporter on PC with Lollypop
