The song was performed in its original show - tune version in the film by American actress and singer Idina Menzel in her vocal role as Queen Elsa . Anderson - Lopez and Lopez also composed a simplified pop version (with shorter lyrics and background chorus) which was performed by actress and singer Demi Lovato over the start of the film's closing credits . A music video was separately released for the pop version . </P> <P> The song presents the ostracized Queen Elsa, who abandons her kingdom when her uncontrollable ability to generate ice is discovered by the public . Up in the mountains, away from the perplexed townspeople, Elsa realizes that she no longer needs to hide her sole ability, and so declares herself free from the restrictions she has had to endure since childhood . She rejoices in being able to use her power freely, to let her past go . Without this hindrance she appears to have more control over her powers and creates a living snowman and a magnificent ice castle for herself . The song also includes discarding items, most notably her glove which her parents gave her to hold back her powers, and taking her tiara off her head and throwing it over her shoulder, afterwards unraveling her braided hairstyle . </P>
