Where did the line 'don't stop get it get it' originate from?

It comes from rapper Luke "I wanna rock (Doo Doo Brown)"

"where i heard it from was Feel Good INC. by Gorillaz"

Luke's song originated in 1991, while Gorillaz's song was in 2005. So Gorillaz copied Luke 14 years later, obviously.

Also, in the song "Still Not A Playa" Big Pun says it. That song was released in 1998.
