At the beginning, the Let It Go children's TikTok song is called "Let It Go".

"Let It Go" is the theme song of Walt Disney Animation Studio's 2013 animated work "Frozen". It was composed and composed by Kristen Anderson-Lopez and Robert Lopez. The song was voiced and sung by American Broadway actor and singer Idina Menzel, the character Elsa in the film.

This song was sung when Queen Elsa left her kingdom and began to create her new kingdom alone in the world of ice and snow. Elsa understands that she no longer needs to hide her ice magic. She announced to the world that she had emerged from the obstacles she had feared to face as a child and was free to use ice magic.

On March 3, 2014, Beijing time (the evening of the 2nd local time in Los Angeles), at the 86th Academy Awards ceremony, "Frozen" won the Best Animated Feature Film Award. The animation theme song "Let It Go" won the award for Best Original Song.

"Let It Go" lyrics:

Well I've loved,I've lost,but I still can't find.Oh the way to the middle of my heart. And I open my eyes and I don't know why.But I feel so old.You don't know what you've got but you've got to let it go.Let it go.Let it go.Let it go ,I know.You don't know what you've got but you've got to let it go.

Well the sun will set on my sins tonight.But the weight's been lifted off my heart. And is it all that much just for me to ask that the truth be told?You don't know what you've got but you've got to let it go.Let it go.Let it go.Let it go,I know.You don't know what you've got but you've got to let it go.

You don't know what you've got but you've got to let it go.Let it go.Let it go.Let it go,I know.You don't know what you've got but you've got to let it go.You don't know what you've got but you've got to let it go.
