The iTunes Store has been a large success no matter how you look at it. Apple has been riding it all the way to the bank since they started and they have hit another one of their major milestones: 10,000,000,000 song downloads. Apple has posted a list of their all time top song downloads here http://www.apple.com/itunes/10-billion-song-countdown/.
