“Let It Go” is an anthem of self-acceptance, the story of somebody learning to embrace the thing that makes them different.

"Best Day of My Life" is a song by American pop rock band American Authors, released on March 19, 2013, by Mercury Records and Island Records as the lead single from their third extended play, American Authors (2013), and the second single from their debut studio album, Oh, What a Life (2014).

Neil Young's 1992 "Harvest Moon" is the followup to his most commercially successful album "Harvest" - 20 years later. "Harvest Moon" was recorded with many of the same original musicians who appeared on "Harvest", such as Ben Keith, on pedal steel guitar, and Linda Rondstadt and James Taylor on backing vocals.

For the very few people who haven't seen Frozen multiple times and know the plot by heart, the song comes at the end of Act I of the film, when Elsa has just run away from her own coronation and set off an eternal winter in her town, Arendelle.
