It's been bugging me for a long time that iTunes doesn't keep songs in its music store forever. Particularly, U2's Live 8 single with Paul McCartney and Bono singing with Alicia Keys on "Don't Give Up" were only available for a very short time. Those of us who didn't know about them at the time, or didn't have iTunes, or whatever, are out of luck. Even if you don't care about legally owning them, you can find torrent downloads of "Don't Give Up," but the only "Sgt. Pepper" downloads are ripped from the Live 8 DVDs, not the iTunes single. I really wish these songs were still available to me in some legal format.
