Crazy in Love

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

Appearance of the 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
The routine has 3 Gold Moves which are all 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, and you can find that here: Beta Elements
 * This is the first song to feature Jay-Z, Umbrella being the second.
 * The dancer seems to be modelling on the catwalk.
 * The catwalk appeared in the actual music video for the song.
 * This is the first Beyoncé song in the game but it's unofficial due to the cover. Her second song would be 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.
 * There is a boy called Wesley Enriquez who designes clothes for the videogame Animal Crossing: New Leaf; one of them takes inspiration from this song (you can see the dress here).
 * 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 choreo had different Gold Moves before.
