Whitney's fan are most proud that she does not lip. That's why there could never be a true comparison, until both artists sing ALL songs live. Whitney performed ALL four songs live on GMA, Mariah performed partially live on Today. Therefore, you can't get a true guage of the voices. What would Mariah sounded like had she sung ALL songs live. Well, we don't know, do we. This performance in Germany is great, because it is live. Throaty voice or not, she is bringing the truth. I would rather hear the imperfect truth, than a perfect lie.
