As a Christina fan myself, her performance fustrated me, her belts were so thin and strained... it's frustating because her upper belts can actually be resonant and pleasant
And of her friends told me she was doing exercises everyday but that won't help at all if you end up straining and screw technique
At least she sings with much better technique on the studio version which means she understans how to sing, I hope she doesn't go too emotional for her next performance
Btw, if someone finds videos for the Top 12 performing post them here!
