She should do the same with hair. First 2 minutes acoustic and then the rest normal version.
I actually like the power ballad she makes out of it. The album version is just a noisy mess salved by a good melody and Clarence's saxophone. I love it, though.
She needs to fix her puking problems, though. Besides looking unhealthy, annoying and making her unconfortable, it isn't good for her voice. I feel sorry for her, she must really be feeling the pressure but she still gives her all.
