The dancer is a woman with short magenta hair in a bob, turquoise pants, aqua platform booties with yellow bows on them, and a multi-colored poncho, which is pink, neon blue, and yellow.
The dancer is standing on a checker-style platform with different shades of red. A large red spotlight shines in the background. Photographs of the dancer ruining various dance routines in the same game also rain down, including those of Good Feeling, We No Speak Americano, and Cercavo Amore.
There are 4 Gold Moves in this routine:
Gold Moves 1, 2, and 3: Lift your right arm and leg, and point your right hand to the right. Gold Move 4: Put your hands beside your head and spin your head in a circle. This is the final move of the routine.
Want U Back is the second routine in which images of past dancers appear, after Teenage Dream.
This dance was played in Cher Lloyd's music video for Oath.
In the picture where the dancer ruins Cercavo Amore, it is only seen in the last chorus way back in the background.
The picture looks like the dancer is kissing the hand of the dancer of Cercavo Amore.
In the downloadable version of Want U Back on Just Dance 4, the line "So I needed to upgrade" was misinterpreted as "Thought I needed to upgrade". This was not the case for the Wii U version and the error was fixed in all future renditions since Just Dance 2015.
In the Wii U version of the routine, the final lyric of the song reads "Just sound like a helicopter/Brrrrrrrrrr...". However, in other versions, it reads, "Does this sound like a helicopter?/Brrrrrrrrrr...".
On all the successive games, the lyric is shown as "Just sound like a helicopter/Brrrrrrrrrr..." for all consoles.
Want U Back is the only routine from Just Dance 4 that was featured on Just Dance 2015 without also being featured in Just Dance 2014.
Want U Back is also the only routine from Just Dance 4 that was exclusive to the Wii U that was available in other consoles.
It is also the only one to return as a downloadable track in a future game.
There are two types of the fourth gold move in the pictograms in the Just Dance Now files, the one with the arrow and the one without the arrow.
The one without the arrow would be a beta element.
There is a glitch whenever the song is present in a Just Sweat mode; whenever the player plays the song, no calories will be counted for. The sweat bar on the top will still be taken in account, however. This is the also the case with Domino.
