I borrow CDs from library, buy from bandcamp and 7digital. I keep audio files on my laptop in a organized folder structure by genre/album and rsync to my Jellyfin. To listen, i play from my laptop to bluetooth speakers and I use the FinAmp app on my iPhone to listen on the road because it has a sweet Offfline mode. Also, i have a nice usb DAC to direct connect (RCA) my laptop to my HiFi system in the basement. I support a local indie radio station which helps with music discovery.
