Jay Z in many ways is a rock artist. In the sense that they've used hard rock, punk rock, psychedelic rock aesthetics and influences in their music. When you see Kanye West, he has a full band playing. Jay Z has a full band playing with Marshalls.

What I consider to be the barometer for what is a rock artist and what is not, is somebody who has a certain element of blues, even a hint of soul or blues music, derivative of African-American blues, folk, spiritual, or gospel.

The term "rock" has, unfortunately, become appropriated by four-year-old girls and accountants. An accountant does something amazingly well on the stock exchange and his buddies high-five him: He's a rock star! A four-year-old girl learned to ride a bicycle: She's a rock star!

There have been times in my life where I was asked to do things and I didn't feel comfortable with it.
