I put in the 70s but the 60s has some great stuff, 80s too... 90s though is just a lot of trash comparatively speaking. I never understood the fascination of a bunch of cursing and yelling to where you can't make out most the crap being tossed out there around the track being laid down with it. But I'm not surprised to see that one get so much considering a general age group here. I'm 30, almost 31, but to be honest I didn't really care much for the 70s stuff until like 10 years ago or so but have come to see it really rocks out and I'm glad it's well represented in Guitar Hero 3, same with the 60s and some 80s.
