I use a combo of streaming stuff I bought on Bandcamp with their app and playing local files. In addition to albums and EPs, I have bought a lot of singles on Bandcamp. I put all the singles in a giant constantly growing playlist on the Bandcamp app and then set it to random shuffle. It takes more effort than using something like Spotify, but I personally like it a lot more because it's only full of music I know I like and I feel satisfied because I supported the artists I like.
I'm waiting for some FOSS developers to hack this thing and run custom firmware on it. Or someone who creates their own "Car Thing" using an Arduino or Raspberry Pi.
