Britney Spears: "Till the World Ends"

Click to listen to Britney Spears' "Till the World Ends"

You want a party song, call a partier. Written by Ke$ha (with Max Martin and Dr. Luke), the second single from Femme Fatale is ginormously pumping uber-Euro uber-disco: sky-sucking synth streaks, a beat that sounds like blimps fucking and a thousand shirtless drunken sailors chanting along on the chorus. Her gauzy vocals kind of drown in the tsunami track. But so would Pavarotti.
