The reporter mentioned signal, though the gov spokespeople didn’t seem to recommend any specific app

I still use bandcamp a lot. Rip CDs I get from other artists directly. Rutracker for stuff that’s unavailable from the artist or label. On my PC I use jriver to organize and listen to my digital audio library. I use syncthing to send selected files to my mobile. On my mobile I use SicMu player. This system works pretty well for me and it strikes the right balance - supporting artists when I can, getting a variety of high quality files, not paying for any streaming service, not having physical clutter… and it’s fun to curate my mobile playlist. Feels like the good old ipod classic days.
