She does it, and she knows it. If she wasn't able to sing very well she wouldn't do this "scream"; she's the queen, her voice not. But after 25 years on stage, i think we could all salute her. Everything she did was amazing, so just shut up and learn about her.
MARIAH SUCKS. Madonna is just the best, mariah will never be able to do what THE QUEEN does. I'm so not sorry, it's human nature.
