I don't think Bey will use the same style routine for the VMA's, especially if she does "Sweet Dreams." It's not at all similar style-wise to the other songs she had the two back-up dancers on.
OMG, how can Beyonce, who's been around for 11 years and always making great music, be worse than a average debut artist with some luck like GaGa who can't sing (and there are some delusional people that compare her to Xtina's epic voice.... ), can't dance (just look at any video or performance where Bee dance and see what's dancing), and is a bad performer (Beyonce is million times better live in every way) - everyone says she's amazing just cause she dresses weird?!?!?!?!?!?!?!?!?!?!?!
