Let It Go

"Let It Go" by Disney's Frozen is featured on Just Dance 2015.

Classic
They're basically Anna (P1) and Elsa (P2) from the movie Frozen. Anna wears her pink cape, black and blue dress, and black boots, and Elsa wears her light blue sequin dress.

Sing Along
She's basically Elsa from the classic routine. She retains her features.

Classic
During the verses, the dancers are in a snowy forest. During the choruses the background is blue with light blue swirls across the screen. The dancer's reflections can be seen at the bottom. During the bridge, Elsa builds an ice castle. The background resembles the movie.

The floor contains a large light blue snowflake, which highlights and sparkles. Multiple snowflakes appear and disappear in the air. After the second hook, Elsa builds her ice castle from the classic mode. At the third hook, the background switches back to the snowflake floor.

Gold Moves 1 and 3: Anna, cross your arms (Akin to Lollipop). Elsa, put your right hand on your face, like a thinking pose. Gold Moves 2 and 4: For both dancers, bring your arms down forcefully. Anna, face the left and Elsa, face the right.
