Wreckx-N-Effect are best known for this paean to the posterior, which features the classic refrain "All I want to do/Is zoom-a-zoom-zoom-zoom in a boom-boom." Rumors have floated around that a young, pre-Neptunes Pharrell Williams actually produced the song, but actual producer Ty Fyffe laid that to rest. "Me and [Teddy Riley] are the only producers that did that song," he explained. "A lot of people got credit ... shouts out to Pharrell; he was down with the camp back in the day. But he really didn't produce 'Rumpshaker.' No disrespect; Pharrell's a genius ... But he only wrote Ted's rap."
