Kara DioGuardi

There's a lot of craft that goes into achieving a hit song - at the beginning of your career, you're usually more inspiration than craft, and you get great when those intersect. A skilled songwriter can get you to that intersection.

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 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.

I wanted to inspire people not to work under a bamboo ceiling. Whatever you are - yellow, black, white, brown - you don't have to allow your skin to define who you are or how you operate your business. There's not one face to anything.
