Bang Bang

"Bang Bang" by Jessie J, Ariana Grande & Nicki Minaj is featured on Just Dance 2015.

Dancers
This is a dance crew of four young women.
 * P1: The first coach has brown fluffy hair at chest length. She's wearing a yellow sleeveless crop top with a purple fringe outline, bright lavender shorts, pink thigh high socks, and purple knee high stiletto boots. She's also seen wearing a big red and yellow necklace. Her hair makes her look similar to Nicki Minaj.
 * 200.png: The second coach has short red hair. She's wearing a pink strapless bra with a purple bow tie and gold chest straps attached to her pants, dark red patent pants, and red peep toe stiletto ankle boots with cutouts on the back of the heel. She's also seen wearing a pink and gold gem necklace.
 * P3: The third coach has short purple hair. She's wearing a purple and pink sleeveless top with gold belts, a brown skirt, knee high socks where one is pink and the other is red, and brown peep toe stilettos with gold triangles. It looks like Jessie J.
 * P4: The fourth coach has long dark red hair in a ponytail. She's wearing a red sleeveless top that's cropped at the stomach, red shorts with gold patent straps, purple fish net tights, and purple booties with gold patent stripes. This dancer looks the same to Ariana Grande.

Background
The background is shown to be a light up stage (akin to Ain't No Other Man), or a roulette. The floor is mostly red and contains a black circle in the middle. That black circle has a yellow sun pattern. The red part of the floor has shining lights on it. The walls has lines of circular lights and a lighting up "Bang Bang." At some parts of the song, four Ace playing cards with each of the four shapes appear and zoom in behind each dancer. The background also looks like a roulette wheel.

Gold Moves
There are five Gold Moves in the routine:

Gold Moves 1, 2 3 & 4: Shake your arms and lift your left leg. This occurs when the chorus starts.

Gold Move 5: Pose accordingly: P1, raise your arms over your head; P2, put your hands behind your head; P3, put your right hand behind your head; P4, raise your right arm. These are the final moves of the routine.

 * "Booty", the whole line "back-back seat of my car", and "on wood" are censored. The second line refers to sex in the car, and the third refers to a man's reproductive organs. However, "Moscato" isn't, because it's a name for an alcoholic drink.

 * This is not the first time a full line is censored. In American Boy, the line "But I'mma like what's underneath them" is censored (but only in Extra Songs).
 * "Seat of the car" can still be heard, but it looks more like "Police Car".
 * "On" from "on wood" is still heard.
 * 'Cockin' it' is still heard in the line 'Bang, bang, cockin' it' in Nicki's rap.
