Part of the problem I think is that many people have already bought Roar, I really doubt they're going to go and do the pre-order right now and have to pay for Roar again.
She shouldn't have started doing pre-orders until that "new" song was released.
I don't know why Capitol didn't make Prism available for preorder when Roar was released
I know, either that or make it available for pre-order through releasing Dark Horse or Walking On Air. But NOT ****ING NOW when Roar had a 45% lead and was slaying WW.
