Does anybody else think her voice sounds much different?  When I heard the first song in the beginning, I thought, "Why're they playing some other person's song in Vanessa's video?"  I guess it's actually her?  Is she just using more head voice than chest voice?
But in the IDWBB clip, it sounded pretty much like the Vanessa I know (which, btw, was absolutely gorgeous).  Hmmmm.
