Hmmm it's okay...but I can't really judge till I've heard the studio version tomorrow seeing as that video is really bad quality. I prefer Xtina's atm. It really does sound like a Xtina song though, it's not like Pixie at all.
The strained vocals, the flat notes, the messed up low notes, the comedy relief that was her attempt to copy the EXACT SAME high note and runs X did on the original demo... Just NO!
I doubt the GP knows this song was previously recorded by Christina (do they even know Christina still exists?). I'm sure this song is going to be another hit for Pixie.
