You know how people say if you play Pink Floyd's Dark Side of the Moon over The Wizard of Oz, the music syncs up to the movie? Behold, the next great coincidence (or is it?): "Bet It Go." Some genius took a video of Zac Efron singing "Bet on It" from High School Musical 2 and put Idina Menzel's "Let It Go" as the track. It's not perfect, but the way Efron's actions line up with the lyrics is absolutely spot on. He seems to be dancing and singing with such conviction that he really wants to let it go! Listen, Frozen is great, but this might be even better.
