Thanks, man, that was good for a laugh. Definitely wiped out any memory of "canonical" chord progressions from my recent auditory memory. It's like "bulk erase" for auditory memory :-)
(I guess I'm more of a "prog/symphonic metal" guy than a screamo/"cookie monster metal" guy, though)
However it is still plain old 4/4 stuff in meshuggah, despite the impression...
