Keep On Dancin' Till The World Ends

So Britney may not be the "dancer" she used to be, but I don't care.  She's probably never performed without lip syncing, and I don't care about that either.  "Till the World Ends" blows every pop song on the radio right now out of the water.  Now I can admit GaGa had her year, but 2011 just isn't it. Move over, cause Britney's back, and better than ever.
