Kinda randomly butting in here, but I joined the forum with this exact thread in mind so.
Anyway, Rihanna confirmed via Twitter that California King Bed is also the single for the United States as well, so I'm confused as to the status of Man Down.
And as for Gaga, I pretty much worship her... which I'm sure won't go over well with some people.
Ke$ha is awesome. She's only listened to for the feel-good party music anyway, and that's her whole image. It's just like BEP's "I Gotta Feeling," is a random occurence because of the fact that sometimes people just want to have fun and forget all their problems. Same concept for "Just Dance," "TiK ToK," and pretty much every Britney Spears song.
