Album: Femme Fatale

Just when you thought Britney's 2011 hit "Til The World Ends" couldn't get better than her scandalous sewer punk chic ensemble in the video, the femme fatale remix dropped. In addition to an opening rap that features Nicki Minaj eviscerating her haters by comparing them to fried chicken, Ke$ha adds a grittier sound to the chorus, and there's even a heavy dubstep breakdown 3 1/2 minutes in. Was it necessary? No, but dubstep rarely is. Embrace the excess and the impending apocalypse (there's always one on the horizon) by playing this loud and dancing shamelessly, almost as if taunting the gods. -Shante Cosme
