Isn't it funny how everyone becomes a world class vocal coach in threads like these. Holding up microscopes to find a crack in an off the cuff. unrehearsed high-note. Stay pressed ladies.
Anyways, Xtina has always had one of the best head-voices in the industry. (As evidenced in songs like Without You, Loving Me 4 Me, Save Me From Myself ect...) This was a pleasant surprise and I hope she utilizes it more in future material.
