Now, I really love this version.

Professional dance is quite something, isn't it? Dancers have to keep an impeccable shape, they have to be really good, the competition is ferocious and they pay is quite horrible and yet, at the end of the day, they and up dancing in the background of the music videos of other artists who are neither as pretty nor as talented as them.
My point is, all I could see the entire video was that the dancers in the back were better than the signers.
