The soundtrack is almost as outrageous as the movie (which, FYI, is about college gals, played by Selena Gomez and Vanessa Hudgens, who commit a robbery to go on vacay): EDM king Skrillex has a huge hand in it, and there's even a rap track featuring James Franco (of course there is!). The only flaw: We wish they'd included the Britney Spears sing-along!
