Ok, now that I'm done freaking out and am able to think about it more...
It probably is a fan edit. If you listen to her vocals during the chorus, you can hear her stopping to catch her breath after she says "human body" similar to how she had to for the SwineFest performance...and I don't blame her 'cause that chorus is a mouthful, but she would've made it go smoother for the studio version.
Nice try though.
