I went with Britney. I know it's a strange choice, but here was my thought process. Madonna and Mariah I eliminated right away because they're in a class of their own. Including them is like including WVU in the list of America's Top Party Schools- it's just not fair to include professionals in a class of amateurs. After they were gone, I think Britney was the most revolutionary of the fluff that was left. You can see her influence in all of the rest the same way that you can see Madonna's influence stamped all over her.
Oh and Beyonce and Alicia Keys ignores me and I don't consider Pink a pop star
