black sabbath don't undo my revision to the black sabbath page again thanks all you're doing is making the page a complete mess with false information i'm sick of having to clean up your crap so knock it off sabbath are not heavy metal as toni iommi himself stated they are hard heavy rock and not heavy metal besides the fact that any moron can hear the difference if you undo my revision again i will just revert it back again stop thinking you know it all you do not i was brought up with these bands and know exactly what genres they are
