The iTunes Signature Challenge

So I made my signature with the iTunes Signature Maker, and...I was curious. How many of the songs can you pick out? Hell, I couldn't pick out some of them. And some, of course, are dead giveaways. But it's challenging in that there are 20 songs packed into 43 seconds of sound, and several repeats of artists (I think there's only 13 unique artists)....
