M.I.A. and Jay-Z may give Katy Perry and Snoop Dogg a run for their money for song of the Summer. They've just released a remix of "XXXO," the first single off M.I.A.'s upcoming album /\/\/\Y/\ (don't ask me to pronounce that title). The original song was already catchy on its own, but with Jay-Z spitting additional lyrics on this revamped version, I love it even more. Between the chorus and the iPhone and Twitter references, something tells me we'll be hearing this on Gossip Girl come Fall. Get your dance on when you read more.
