Some of y'all are so damn clueless. Who gives a rat's azz whether an album is #1 on itunes? That does not guarantee that it'll debut at #1 on Billboard. You have amazon, pre-orders from artist's site, in-store purchases(target, best buy) etc Britney's tour was not sold out, they lied to you boo boo. That would have to go to Taylor Swift. So my money is on her or Beyonce.
