The routine is performed by a dance crew of four young women.
P1 has brown curly 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. She resembles Nicki Minaj.
P2 has short red hair, which is longer on the right side of her face. She wears a light-red 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 has short purple hair in a bob. 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. She resembles Jessie J.
P4 has long maroon hair in a ponytail. She wears a red sleeveless shirt that exposes the midriff, red and gold drum-like shorts, purple fishnet tights, and purple stiletto ankle booties. She resembles Ariana Grande.
The background is shown to be a light up stage (akin to Ain't No Other Man), shaped like a roulette wheel. The floor is mostly red and contains a black circle in the middle, which 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.
There are 5 Gold Moves in this routine: Gold Moves 1, 2, 3 and 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.
This song was announced during the "MTV 2014 Video Music Awards" via Twitter along with Black Widow.
This song is the latest-released song to be featured on Just Dance 2015. It was released on 29 July 2014 which is later than any of the songs in the same game.
This is the only Jessie J song that is a dance crew, along with being the only to not be a solo routine.
During Nicki's rap, Myx Moscato is misspelled as mix Moscato and it's frizz in a bottle is misinterpreted as it's friends in a bottle. Also, hourglass appears as hour glass in the beginning of the song.
In the game, P2's hair color is red but her avatar has orange hair.
Jessie J and Tyler Oakley count as one dancer on the World Dance Floor when seen as a Just Dance VIP. Tyler plays as P2 and Jessie J plays as P3, although both of them are counted to be playing as P4. Their avatar is that of P1 for Aquarius/Let the Sunshine In.
However, on Wii, the video for Tyler and Jessie is not played (like all other VIPs on the World Dance Floor).
There is a glitch where whenever P1 and P4 on some moves lower to the ground their eyes turn black, but they return white when they stand up (this happens on all consoles).
In Rabiosa’s Mashup, the Beta version is used (their eyes are visible).
Along with some other routines, when this routine is viewed from the dash.justdancenow.com link, the Gold Move effect will not appear in the video that is shown.
When the coaches perform this move, the remote control versions of the routine track the player's moves as if they were doing this one.
Bang Bang has the most watched preview on justdancegame’s official YouTube channel. As of November 14, 2017 the video has 2,807,398 views.
