"Let It Go" is a song from Disney's 2013 computer-animated feature film Frozen, whose music and lyrics were composed by husband-and-wife songwriting team Robert Lopez and Kristen Anderson-Lopez. 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. It was later released as a single, being promoted to adult contemporary radio by Walt Disney Records in January 2014. Anderson-Lopez and Lopez also composed a simplified pop version which was performed by actress and singer Demi Lovato over the start of the film's closing credits. Disney's music division planned to release Lovato's version of the song before Menzel's, as they did not consider Menzel's version a traditional pop song. A music video was released separately for Lovato's version.

Robert Lopez is an American songwriter for musicals and playwright, best known for co-creating The Book of Mormon and Avenue Q, and for co-writing the songs featured in the Disney computer-animated films Frozen, its sequel Frozen II, and Coco, with his wife Kristen Anderson-Lopez. He is one of only nineteen people who have won an Emmy, a Grammy, an Oscar and a Tony Award, nicknamed by Philip Michael Thomas in 1984 as the "EGOT". He additionally holds the distinctions of being the youngest person to win an EGOT, and winning the awards across the shortest period of time: he won all four in the span of ten years and completed the set at the age of 39. He is also the only person to have won all four awards more than once, having won two Oscars, three Tonys, three Grammys, and four Emmys. With a second set of competitive wins beginning with his June 27, 2010 Emmy and concluding with his March 4, 2018 Academy Award, he has broken his own 'fastest to complete' record, establishing a new fastest EGOT interval at 7 years and 8 months.
