M.I.A. lived fast and died young in her last hit, "Bad Girls," now she's back and she's all about freedom (or, as she sings, "Dem-dem-dem-free-free-dem!") The banger is heavy on the drums and the video takes place in the coolest underground rave we've ever seen. Then again, we'd hang out with M.I.A. at any party she invited us to.
