Katy Perry's single was based on shock value, now that she has a hit single, the shock is gone.
(unless you're talking about the shock of people liking it, thats still there)
No, I meant why do you write all that and even say that she should shut the hell up, right after you point out that you don't care. Why post if you don't care? Also, I'd rather hear her rather than more shit from Miley Cyrus and The Jonas Brothers.
