The Oscars are all about pageantry, but oddly they don't feature musical performances of the Best Original Song nominees every year.  Part of that is for a show that's always worried about running long on time, but perhaps it's better to cut one of the 18 self-congratulatory tributes rather than the live performances.  Thankfully, the Academy will be embracing their Best Song category this year.  Pharrell Williams was already announced to perform "Happy" from Despicable Me 2, and now the show will also feature Idina Menzel performing one of the biggest hits of the year, "Let It Go" from Frozen.  Since Williams was already tapped to perform, it's not surprising that the Oscars would also go after a singer for another nominated song, and it's certainly not surprising for "Let It Go", which is the clear frontrunner in the category.  It also helps that the album is the longest-running #1 soundtrack since 2003, and Disney has held sing-along screenings.

In case you need to hear the amazing song again, hit the jump to watch the scene from Frozen.  The 86th Academy Awards will be held on Sunday, March 2nd.
