Black Heart?

[Proxy]

>_< I Love this song, but I don't know who it's actually by. I've heard 3 different bands that people claim have done it.
1) SlipKnot
2)Stone Sour
3)V-Mob
and i dunno which of the 3 (if any) do it.
(if you couldn't tell by the bands, it is a metal song)
and help finding the true artist of this would be greatly appreciated, thanks a tonne!
