I especially love the pump organ on "Walkin' on the Road (to the Future)" and "The Wonder Won't Wait"-it adds this wheezing, groaning sound. It's almost as though another person, another set of lungs, is suddenly in the room.

Although they can do it all the time, you know, they're far better than me, on a musically, on a theoretical music level. You know, they're out of my league.

What I like about Elvis is the same I like about James Brown, Michael Jackson, Prince. These guys, back in the day, there was no smoke and mirrors. It was just raw talent.

I always say I wanna work with Alicia Keys. I'm in awe of her.

I grew up on the Beatles; I love Linkin Park and Green Day. I heard hip-hop for the first time at 11 and realized what I was missing.

One element of Madonna's career that really takes center stage is how many times she's reinvented herself. It's easier to stay in one look, one comfort zone, one musical style. It's inspiring to see someone whose only predictable quality is being unpredictable.
