We Made You was the first single. That's what it was released as. Why the didn't count crack a bottle as the first single. idk. From what i remember that came out a long time prior to Relapse. And it was just Em's first song in a long time so once it was played on radio they wanted to try to sell it on iTunes and it did well.
Katy finally where she belongs
I can see her doing at least 5 weeks ( having the next 2 on lock because of the video) and there isn't really a big competition for her right now. I hope Roar is #1 for more weeks than IKAG
