Parents everywhere are bracing themselves: The track listing for "Frozen II" was released today, featuring artists like Panic! at the Disco, Kacey Musgraves and Weezer along with the main cast, and we're all waiting with bated breath to see what the next "Let It Go" will be. The roaring 2013 Disney success resulted in the explosive popularization of the signature tune, with kids -- and parents -- the world over belting the lyrics for...ever. Idina Menzel (who voices Queen Elsa in the films and is responsible for the vocals behind "Let It Go") called the song "one of the great gifts of [her] career" and explained that the music in "Frozen II" is going to be just as moving. "'Into the Unknown,' and then there’s another song called 'Show Yourself,' which is pretty spectacular as well. Everyone always asks is it the next 'Let it Go'? That's lightning in a bottle," she told The Hollywood Reporter. Can you still identify the songs from the first film?
