Beyonce is so skilled, great technique, the AGILITY that her voice has, etc. I'm sorry but at no point could moo do it. I just clicked this perform ance of hero thst Ray posted and Even that was on the verge a lol bit. Her vocals seem so labored until she got to her register. Mariah doesn't give an EFFORTLESS vocal. Sumn Whitney and Beyonce both give LOLZ
