P1 is an animal mascot, being a yellow pig. He wears light grey overalls with pink chains, with one pendant including a unicorn.
P2 is one of the showgirls in the choreography. She wears a blue jean collared crop top with orange fringe, and her skirt is also the same; blue with orange fringe. She also wears orange leggings underneath, and blue booties. She has long orange hair with a faded orange cowboy hat.
P3 is the other showgirl in the choreography. She wears a bright blue bodysuit along with a pink one piece with two red shoulder pieces. She also wears red boots, and a pink gold and black hat. Her hair is in a short black bob.
P4 is a human-unicorn. His head is pink with a blue mane, purple lips, and yellow eyelashes. He wears a pink tank top, and dark pink loose pants. He also wears black converses.
The background is an American rodeo show act, with fire shooting from the sides of the floor. The floor also has red, white, and blue patterns with stars all over, displaying the pattern of the American flag.
There are 3 Gold Moves in this routine, all of which are the same: P1: Hit the air with your right hand. P2: Shake your hand to the left and kick your right foot was you move forward. P3: Raise your right hand up to your head as you walk up forward. P4: Put your hands on your hips.
All the Gold Moves are done from left to right and require each player to move forward.
This is the second song by Miley Cyrus in the series after We Can’t Stop.
However, We Can’t Stop was taken out of Just Dance 2014 and put in Just Dance 2015 as a DLC, making 4x4 the first song by Miley Cyrus to be officially released in the series.
The words banged, piss and hell are all censored.
All three words are replaced with whip cracks.
Nelly's part was cut from the version used in game.
However, he can faintly be heard at the end of the bridge saying "Yeah."
At the end of the first verse, there is an inaudible word. It appears as recent pills.
Some websites suggest it is "pussy tails", or "rooster tails".
At the beginning of the original song, the footstep sound is heard 4 times. The YouTube gameplay, anyway, features the footstep noise 9 times. Nonetheless, the in-game version has 4 footstep sounds.
There is no DLC dancer in the Mashup. This is the only Mashup of Best Of themed in Just Dance 2015 to not feature a DLC dancer. It is also the Mashup that doesn't have Gold Moves like the other themed Mashups.
Coincidentally, mashups from Just Dance 4 had no Gold Moves at all.
P2 looks very similar to Cotton-Eye Joe. However she is not the same dancer, as Julia Spiesser left after Just Dance 4.
The lyrics, "Who can't you tell?" was changed to "Can't you tell?" but you can still hear "Who."
In the Mashup, the dance starts as soon as the song begins.
The entire second verse does not score any moves on remote consoles.
P3 greatly resembles one of the right dancers from Gangnam Style with the hair.
