The other version of this song's intro was way more complicated than it had to be and
the heavy part was wrong. So here's my version...It sounds good to me when I play along
with the CD.
Drop D tuning. I know the band doesn't use this tuning in the entire CD but I'm pretty
sure they use it for this song because it sounds perfect.
