Crazy in Love

"Crazy in Love" by Beyoncé ft. Jay-Z (covered by Studio Musicians in-game) is featured on Just Dance 2, Just Dance: Greatest Hits and Just Dance Wii.

Dancer
The dancer is a woman with brown curly hair, a purple and black dress with a gold belt, purple strappy heels and sunglasses.

Background
It resembles a catwalk that a model would walk down. In the beginning of the song she struts her stuff down the catwalk before starting her dance, making it apparent that she is supposed to be a model. The background consists of flashing lights. There are packs of small circular lights on the wall and stage lights on the floor.

Gold Moves
There are 3 Gold Moves in this routine, all of which are the same:

All: Make a big circle with your right arm.

Trivia

 * The dancer appears in the background of D.A.N.C.E. with blue skin and without clothes' color.
 * The song had a different color scheme and longer hair before; you can find more information here.
 * This is the first song to feature Jay-Z; it is followed by Umbrella.
 * The dancer seems to be modelling on the catwalk.
 * The catwalk appeared in the actual music video for the song.
 * This is the first song by Beyoncé in the series; however this is unofficial because the song is covered. It is followed by Beautiful Liar, a song which was also covered.
 * The green lines representing hand movements in the final version of the dance may have come from the beta dancer, which had a green glove. This (the lines) was not changed despite the fact that the final dancer's glove was changed to orange. It has been fixed in the Wii version of Greatest Hits.
 * The caption "Just Say NO!" has the same name as a Barbra Streisand caption.
 * Wesley Enriquez designed a dress inspired from this song for the videogame Animal Crossing: New Leaf called Crazy Dress.
 * If you watch the preview gameplay on YouTube, you can notice that there is one incorrect pictogram, the Gold Move pictogram. The strangest fact is that it's not golden, so maybe the routine had different Gold Moves before.
