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.

The Best of Elvis Presley, Doris Day, Jerry Lee Lewis, Bill Hailey and the Comets, Frank Sinatra, Peggy Lee, Frankie Laine all topped the charts in the '50s. Load a playlist of rock n' roll royalty. You're spoilt for choice.
