You know how some people really get into singing. I mean, their faces just show how so into it they are? Expression is everything, right? I remember as a little girl, wanting to be a famous singer someday. And of the famous singers I knew from back in the day, they were all expressive in their singing. So, contorting ones face up whilst singing must be popular. AND it must be in the genes.
This girl gets into it when she sings...face and all. :)
