She's getting better and better at it the more she sings it.
As an aside, I was listening to Kelly's Breakaway album last night in the car on my way home from working late and really listened to how she emoted in the way she sung certain songs and certain sections of songs and she really has become a very accomplished singer. If you don't listen closely for it, you can't really appreciate it, but I did last night. She is really amazing.
Kelly really is a very talented young woman. I love to listen to her sing, even though some of her music isn't my style.
