But that doesn't mean game over for everybody else does it? And I disagree, I don't think madonna has done it all - I think there's so much more that she could do, and that is yet for her to do - and I'm sure she would agree.
However I do totally agree with you that no other female artist has had as much impact as Madonna - but that doesn't mean it's all over!
I'm not saying the game is over for everyone as it clearly isn't. But Madonna was the first female artist to do everything that the men were. Thats why her impact on musical culture will never be topped. For example, The Blonde Ambition Tour completely changed concerts. That set the blue print for every tour a pop star has had since. Thats a legacy.
