Depends on who you're listening to. For mainstream artists they'll post a store link when an album comes out and you can get the tape or whatever directly from them or an online retailer. Most of the psychical medium options come with a free mp3 album. If they're indie I get stuff from their Bandcamp page. If I just want one mp3 song ill go to amazon and pay the $1.20 or whatever. Google Play stopped letting you buy files and apple's stuff has to be converted sometimes to run on your mp3 player. They're all moving to/pushing the subscription models tho which sucks.
