The dancers are based off of Anna and Elsa from the movie Frozen.
P1 (Anna) has strawberry blonde hair in braids and wears a maroon velvet cape, a black and blue dress with a light blue long sleeve shirt, and black lace up boots.
P2 (Elsa) has platinum blonde hair in a fishtail braid and wears a light blue dress with mesh sleeves and a mesh cape, and light blue kitten heels. She is also the solo dancer of the Sing Along routine.

The official logo for Frozen first appears. During the verses, the dancers are in a snowy forest. During the choruses, the background is blue with light blue snow swirls and snowflakes across the screen. The dancer's reflections can be seen at the bottom. During the bridge, Elsa builds an ice castle. The background is based off of assets from 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 routine. At the third hook, the background switches back to the snowflake floor.
There are 4 Gold Moves for each coach in the Classic routine:
Gold Moves 1 and 3:
P1: Cross your arms.
P2: Put your right hand on your face, as if in a thinking pose.
Gold Moves 2 and 4: Bring your arms down forcefully.
Gold Moves 1 and 3
Gold Moves 1 and 3 in-game
Gold Moves 2 and 4
Gold Moves 2 and 4 in-game
There are 2 Gold Moves in the Sing Along routine, both of which are the same:
Both Gold Moves: Throw both arms forward while stepping to the right.
This song was leaked on both the PAL and NTSC box covers.
However, only the NTSC cover mentioned the specific song. The PAL cover only mentioned the 'artist'.
The song was revealed briefly in a private YouTube video.
The dance features several elements from the movie, including the background and the dancers (Anna and Elsa) are similar to their cartoon form.
This is the second time that a movie title appeared before the routine. This comes after Prince Ali.
In the Coach Selection menu, Anna has her hands on her hips, but her pose was supposed to be crossing her arms.
A very short part of the Sing-Along was found in a Vimeo showreel, making this choreography leaked.
Both modes for this song were leaked.
Elsa leaves ice trails whenever her arms or hands are in action.
"The past is in our past", instead of the correct "The past is in the past", is seen in the lyrics.
This is the only female/female duet in Just Dance 2015 (recycled DLCs not withstanding).
This is the final track to be revealed through a gameplay on the Just Dance YouTube channel.
It is also the only track in the main track list to be revealed after the game's release and the final track list's reveal.
The lines "Don't feel" and "Here I'll stay" in the Sing Along routine become immediately unhighlighted after they are sung. In the Just Dance 2015 China version of the Classic routine, the Chinese line for Couldn't keep it in/Heaven knows I tried gets immediately highlighted, although Weina sings it slowly.
In the sing along, the song is titled "Let It Go" with quotations (the classic routine not having quotations) and the artist is "Disney Frozen" instead of "Disney's Frozen". Also, in the preview of the store, it shows "#Disney" on the corner.
On 舞力全开2015, a Mandarin version of the song is used. The title is written as "随它吧". It is currently the only Western song to have its audio altered for a foreign game, and one of the few times for any game.
On the Xbox One, the sing along routine came out roughly a month after it did on the other consoles.
This is the only song on Just Dance 2015 to have a downloadable alternate routine.
For some reason, the square of the Sing Along version is different in the shop than in the menu; it shows the dancer in a different pose and it can be seen that the dancer has lipstick. The lipstick is not present in the routine.
This also occurs to I Need Your Love, as the square shown in the shop has a different background than the square shown in the song selection menu.
Similar to other songs with copyrighted dancers, being Prince Ali and Ghostbusters, the song does not come with an avatar that is based off one of the dancers in its debut. Instead, it comes with a snowflake avatar.
The song's pictogram bar beats at 69 bpm, even though the song’s actual bpm is 137.
In Just Dance Now, there is a glitch when playing the Classic routine; when the last Gold Move occurs, the Gold Move effect does not appear; however, its sound plays.
On the Just Dance Now menu, the Classic routine was accidentally placed before Kaboom Pow for a short period of time.
In Just Dance Unlimited and Just Dance Now, the song name for the Classic routine is "Let It Go". However, this is not the case with the Sing-Along version of the routine. Instead, the song name for the Sing-Along version is Let It Go - ALTERNATE/Sing-Along without any quotation marks.
The quotation marks were later removed in Just Dance Unlimited for the Classic routine in April 2016.
In a Behind-the-Scenes version of Boom Clap, the Alternate is incorrectly labeled as On-Stage.
Let It Go is labeled as "Top Track" in the Just Dance Unlimited section of the official Just Dance 2017 website. However, its representative picture shows the Alternate version instead of the Classic one, with almost completely absent user interface.
In spite of that, when one clicks on the picture, the site opens the preview gameplay for the Classic version.
Additionally, the picture is named "frozen_288762.jpg", instead of using the actual song title.
The Sing Along version is the last DLC in the Just Dance series. From Just Dance 2016 onwards, they are replaced by Just Dance Unlimited.
On Just Dance 2018 via Kids Mode, P1 has an unfinished avatar which only portrays her cape; P2's avatar, instead, is replaced by the snowflake avatar in Just Dance 2015.
The album background is different from the background in the menu icon.
