Apple just sold their ten billionth iTunes track, and to go along with the festivities, they’ve released a list of the 20 best-selling tracks of all time that have been purchased from the iTunes Store. We’ve got the list for you below, which we find fairly interesting. I mean, I Gotta Feeling is both fairly new in the grand scheme of things, and also pretty sucky, and yet it’s the most downloaded track in iTunes history. Also, Flo Rida gets two spots on the top 20, which ties him with Lady Gaga, The Black Eyed Peas, and Katy Perry for most appearances on the list.
