Kara DioGuardi

I don't think people really understood what I did. And you know, in my book, 'A Helluva High Note' deals with my back story, that I was a songwriter, that I spent years trying to hone my craft and being rejected and then finally becoming a successful songwriter, record executive and publisher.

I've never in my life bought a big piece of jewelry - like, 'I'm gonna get myself a big piece of jewelry!' Songwriters' lives are unstable and up and down. Even though mine has sort of has followed more of a going toward the sky trajectory.

I think Bruno Mars is a great example of a great voice and classic songwriting with a twist that makes it contemporary. I think he's done a great job of it. I think Katy Perry has undeniable songs for what she does, for that pop market. And, if we're talking in the truly pop market, I would say those two.
