Which Just Dance game features the song 'Let It Go' from Frozen?

Just Dance 2015 features “Let It Go” from Disney’s Frozen. The game includes a “Let It Go” routine and a separate sing-along alternate version associated with Idina Menzel’s performance in the film.

Frozen premiered in 2013, and “Let It Go” became the movie’s signature song. In the English-language film, Elsa sings it as she leaves Arendelle and builds her ice palace, with Idina Menzel providing the singing voice. The song was written by Kristen Anderson-Lopez and Robert Lopez and won the Academy Award for Best Original Song.

The Just Dance version can cause confusion because later games and regional editions also used Frozen-related material, and the franchise regularly adds songs through downloadable or subscription catalogs. For this question, however, the standard game entry is Just Dance 2015. The soundtrack also included other major 2014-era hits such as “Happy,” “Bang Bang,” and “Bailando.”
