Idina Menzel - Let It Go (from "Frozen")

Hey, do you guys know this is the catchiest song I have ever heard. That message is good and all.

"Let It Go" is a song from Disney's 2013 animated feature film, Frozen, with music and lyrics composed by Kristen Anderson-Lopez and Robert Lopez. The song was performed in the film by American actress and singer Idina Menzel in her role as Queen Elsa, after an ostracized Elsa abandons her kingdom when her magical ability to create and control ice is discovered by the public. Up in the mountains, away from confused and suspicious onlookers, she realizes that she no longer needs to hide her abilities, and declares herself free from the restrictions she has had to endure since childhood. She rejoices in finally being able to use her powers without fear, manipulating snow and ice to generate a magnificent castle for herself.

"Let It Go" won the Academy Award for Best Original Song at the 86th Academy Awards, where the song was performed live by Menzel. It is the first song from a Disney animated musical to reach the top ten of the Billboard Hot 100 since 1995, when Vanessa L. Williams' "Colors of the Wind" from Pocahontas peaked at number four on the chart. The song is also Menzel's first single to reach the top 10 on the Billboard Hot 100 chart, making her the first Tony Award  winner for acting to ever reach the top 10. 

On December 6, 2013 Walt Disney Animation Studios released a video of the entire "Let It Go" sequence as seen in the movie, which has over 184 million views as of April 13, 2014.
