The best part of Frozen was just released onlineS

The absolute, hands down best part of Frozen is Broadway legend Idina Menzel's ballad "Let it Go". It's just absolutely triumphant, and also showcases one of the most emotional moments of the whole film, when Elsa the Snow Queen gets to do her hair the way SHE wants. Let it go, girl.

Watch for yourself:
