Spaz

Pharrell Williams explained to Rolling Stone this not very PC song title: "Our fans want to jump around and go spastic. Hence, one of our new song titles: 'Spaz.'" In England, the term is a derogatory reference to someone with cerebral palsy, in America it is more often used to describe someone with a great deal of uncontrolled energy.

This was used in the soundtrack in some adverts for the Microsoft Zune digital products.

N.E.R.D are Pharrell Williams and Chad Hugo, whose day job is the production duo The Neptunes, plus their sometimes vocal partner and drummer Shay Haley. N.E.R.D stands for their basic belief that "No-one Ever Really Dies." Among the numerous hit songs The Neptunes have production credits for are "Rock Your Body" for Justin Timberlake, "Hot In Herre" for Nelly and "I'm A Slave 4 U" for Britney Spears.
