Watch Idina Menzel Belt Out "Let It Go" at the Oscars

John Travolta may not know who she is, but we love Idina Menzel. The songstress appeared at this year's Oscars to perform her smash hit from Frozen, "Let It Go." The track has been imitated so much since the movie's release, but no one does it quite like Idina. Watch the performance again (and again and again) below.
