Listen to "Let It Go"

Visit either the "Frosty Magic" or "Fun in the Snow" Dream Stages when using your Dream Book. To the right of the starting position, you will see a blue snowflake/musical note icon. Walk over to it, and you will be given the option to "change the background music". Do so, and you will be able to hear the song "Let It Go" from Frozen in its entirety.
