You mean Hot 100 top tens after the breakout hit? Katy broke it with her third song. She have 10 top tens starting with "Waking Up In Vegas" and that's great!
Explanation why it is underperforming? I've noticed that It was getting a lot of love from ATRL members but not from radio or the public(ITunes/amazon).
Is Bruno performing at AMA? If he is performing should he perform Gorilla or a new song?
Bruno said he wanted to experiment with Gorilla and it didn't work. I thought regardless of which song he's going to release radio will play it. I was wrong.
