This is basically what I think the intro is or is similar to for this song.  
The other tabs that are out there are great but they lack the intro.  
I think this is at least close to what it's supposed to be so if anyone could 
correct it and maybe help out and get us a perfect intro, that'd be great.  
This is all palm-muted, I'm almost positive.  It's played pretty quickly as well.  
Good luck.
