In reply to Stephy..

You sound dumb. Mariah Carey has shown time & time again that she can deliver a 5 octave range LIVE. Period. Whitney Houston is a powerhouse singer. Mariah is not a powerhouse in the studio or live. She is an alto-soprano with a whistle register. Whitney Houston is a mezzo-soprano with a powerful voice. Where as Mariah has a light voice. That does not make her a studio vocalist just because she does not have Whitney's power. Saying Mariah Carey is not a vocalist is saying Janet Jackson is not a dancer. GOOD BYE.
