You can get a ZIP of OGGs if you want. Those will last as least as long as a 2005 DVD rip from Pirate Bay. Feels good.

(You can also stream through their site and app, and I think they have all sorts of social features... but you can ignore the hell out of it and just get tunes for money. Really one of my top 5 sites, Bandcamp, though I wish they were still independent.)

Zip of FLACs even. As space is cheap and abundant (or at least for me, buying only about 6-12 albums / month) that allows me to not worry about transcoding into whatever at some point in the future.
