Baby One More Time

"Baby One More Time" by Britney Spears (covered by The Girly Team in the game) is featured on Just Dance 3, Just Dance Wii 2 and Just Dance Now.

Dancers
The four girls appears to be high-school girls; just like in the music video, and cheerleaders. Their dresses have the same design but different colors and different hairstyles, but they're all blondes (black hair in Just Dance Now).

P1
 Player 1' s dress is red (sky blue in Just Dance Now). Her hair is short. She also wears a pink hair clip in her remake.

P2
 Player 2' s dress is purple (lime green in Just Dance Now). Her hair is quite long.

P3
 Player 3' s dress is blue (orange in Just Dance Now). Her hair is tied in two pigtails.

P4
 Player 4' s dress is green (dark pink in Just Dance Now). Her hair is long too.

Background
The girls might be dancing in a locker room or a school corridor since there are lockers in the back. The floor is checkered and the brick wall is pink. A school bell can be seen too. The lockers are occasionally light up and opens/closes the doors. The same goes for the floor.

Trivia

 * This is the first ever all female dance crew. It's also the only all female dance crew on Just Dance 3.
 * The girls were originally not going to freeze in the air during the jump in the end as shown here . The girls "land" the jumps and the Gold Move is removed.
 * During the first gold move, the dancer in red looks like is about to fall, but she scoots her leg over, and regains her composure. Also in the beginning of the song, she does a completely different leg motion than the other girls.
 * There is a dancer with pink pigtails that appears in the mashup. It's currently unknown for what song she was supposed to be in.
 * The green girl (The pink girl in the JDNow Version) is the same as the dancer from Boom.
 * In the Mashup, there are only 5 different dancers.
 * Just Dance Now's remake made dancers the inverted colors.
 * In JDNow, a few lines disappear too quickly and they get replaced by the following one; surprisingly, they don't get highlighted until they're sung.
 * The dancer from I Don't Feel Like Dancin' is the only male dancer in the Mash Up.
 * In Just Dance 3, sometimes, the song finishes very suddenly and it gets replaced by the score showing.
