I don't want Birthday to be next single I don't see it becoming a smash (maybe in US but not worldwide).
I'd prefer Legendary Lovers, Walking On Air, Ghost or It Takes Two.
people keep posting about allah and "the quran" which I am lead to believe was the least popular album ever! since i cant find a single song from it on itunes. hell, can't even find a picture of this allah guy, for someone with so little media coverage you people are pretty damn quick to assume this was about him. Katy is way too classy to be dissing some 3rd class celebrity. I'm sure your mistaken. lets drop the drama and just enjoy the song.
