Spectronizer

Spectronizer is a japanese superhero song whose first appearance was in Just Dance 3. It made an appearance in Just Dance Wii 2 as well.

Appearance of Routine
The dancers might be teenagers, and since they're superheroes, they have suits that matches their colourscheme. P1 is the only girl and she's wearing a magenta jacket under a black dress. She has a blue tie, blue shoes and a blue diadem. P2 seems to be the leader. He wears a black and red shirt with red pants and black shoes. P3 wears a yellow vest over a black shirt and black pants. He wears glasses and yellow shoes. P4 wears a blue shirt and blue pants, blue shoes and a blue hat. He wears a vest too but his is unbuttoned. All of them has black hair, presumably to resemble japanese dancers. They're dancing infront of a pink 2D city with skyscrapers and cliffs. It almost looks like blueprints/drawings. A giant robot and a monster can be seen attacking or dancing.

Gold Moves
The routine contains four Gold Moves. All dancers have one unique Gold Move, but the other three are the same for all the four dancers. The three mutual are a superhero pose (swing your arms in the air and put the right hand on your chest and then directly swing your arms again and put your right hand on your back instead).
 * (P1 Personal) - Do peace signs with your hands.
 * (P2 Personal) - Put your arms in a mirrored "L".
 * (P3 Personal) - Pull down your right arm slowly on the side.
 * (P4 Personal) - Bend your right leg and put the left infront while putting your right hand in the air.
