Dr. Dre plays a key role in one of Apple's most important businesses, Apple Music chief Jimmy Iovine told Variety in an issue published on Tuesday.

Rapper and producer Dre (Andre Young) rarely speaks in the course of his duties at Apple, but he talks to Iovine every morning, Iovine said in the interview.

"Dre's purpose in life is to come up with something that moves the needle," Iovine told Variety. "He's done that really seriously a bunch of times. And now he's experimenting with video. And what he does will be unique, and he will get there. My responsibility to Apple and to him is to put him in that position where he can."
