Heavy Rotation

"ヘビーローテーション" ("Heavy Rotation") by AKB48 is featured on Just Dance Wii.

Appearance of the Dancers
The dancers are both girls with the following features:

P1
P1 has blue hair in two pigtails. She wears a pink shirt with a light blue tie and navy blue-and-pink vest on top of it. She also has a magenta skirt and pink knee-high socks with black shoes.

P2
P2 has straight blue hair with a light blue hair clip. She has a blue and light blue band uniform. She also wears a periwinkle skirt with magenta on it and periwinkle knee-high socks under a black pair of shoes.

Background
The routine appears to take place in a high school dance or a prom. There is a billboard that says "Just dance show, have fun tonight" behind the dancers, and the floor lights up.

Gold Moves
There are 5 Gold Moves for each coach in this routine:

Gold Moves 1, 2, 4 and 5: Quickly bring your hands down.

Gold Move 3: Blow a kiss with both of your hands.
