The dancer is a woman with pink braided hair, which has blue highlights striped around the sides of her head. She wears a pair of pink-and-black striped sunglasses, a light green-and-blue long-sleeved crop top, a pair of red-and-black striped pants with gold crosses, and a pair of cyan blue shoes. She also wears a gold necklace around her neck. At a few points, she turns black and white.
At the beginning, the dancer comes out of a robot. Then the background has a triangle before the chorus. After this, the background switches to a patterned one with clones of the dancer, highly resembling the music video. In the verses, there are two fuchsia robots like the one of the beginning in front of a background with blue and fuchsia lines, and two other clones of the dancer.
There are 4 Gold Moves in this routine:
Gold Moves 1, 3, and 4: Put both arms in the air, like a flexing pose. Gold Move 2: Pat your chest and take one step back.
The dancer lips syncs the line "You're the truth to me".
In the Mashup, some left armed moves from Video Killed the Radio Star are counted for on the Wii U, while on other consoles, including camera consoles such as the Xbox One, only his right armed movements are counted for. This is abnormal, as the remote's scoring is heavily based off the right arm.
The counted left armed movements on the Wii U usually result in an 'X'.
The issue with non-counted left-hand moves on camera consoles also happens with Pump Up the Volume
The beta appearance of the coach (with lime green shoes instead of teal ones) appears in Party Master modes in Just Dance 2015 and Just Dance 2016, and in Uptown Funk’s background and Mashup.
Even though the coach is not in her beta wardrobe Built For This (Party Master Mode), the Song Switch button shows her in her beta outfit.
The beta coach also has a different outline than the final version. Instead of being a solid outline all around her body, the outline is soft and fades towards her feet.
