The music business, and the entertainment business in general is more visual and beauty oriented than it was years ago. Her album art suggests that she trades on her looks. I am sure that is part of the reason for her success. She is not alone in this. Pop music is totally like this and it is even beginning to creep into classical music. Esp among female solo artists. A lot of mega talented stars from the past would not have a chance of breaking into the music today. Not trashing Miss Krall, she is just a product of the times. And I am sure she makes a good living, so all is well.
