On Wednesday Apple's iTunes service marked a milestone, serving up its 10 billionth song.

The lucky user who downloaded it will receive a $10,000 gift card, which should probably be more than enough to keep his or hers iPod full of fresh tunes for years to come.

Apple also announced that the most downloaded song on the service was "I gotta feeling" from The Black Eyed Peas. The band's rather annoying "Boom boom pow" ranked in third. Outlandishly dressed Lady GaGa came in second with "Poker face," while "Just dance" came in sixth.

We wonder what the lucky 10 billionth downloader picked, but Apple isn't saying. In case you're the lucky winner let us know, once you're done downloading a few thousand free songs.
