Diamonds

"Diamonds" by Rihanna is featured on Just Dance 2015.

Appearance of the dancer
The dancer is a woman with short purple hair, a long sleeve turtleneck, a gold cage girdle belt, pink tights with large holes, and black stiletto ankle boots. At some points she changes black with most of her outfit changing to white and grey.

Background
The background is black with white rising glitter resembling the titular diamonds. At some points a rainbow circular light and a shining white light in the distance shine about. The light is likely to have been caused by the diamonds' reflections of light. At some point during the chorus the background zooms out with the dancer, revealing more diamond covered floor and as the dancer zooms back in strings of diamonds appear in the background.

Classic
Update as we move along.

Seated Dance
One Gold Move has been revealed so far for the alternate.
