Take Lateralus instead of Aenima.....

I think "heavy" is a huge and non-specific word to catalog a music style... sorry I disagree

No Killing Joke? Most angry (and influential) heavy band of all time--the band's band.

Motorhead not in the top 5?

Well, I guess this is a generational thing but I think we need a bit of perspective here: Sabbath, AC/DC, Motorhead need to be on top. Soundgarden? Purleeese! Not sure which MBV track we're talking about but Mr Shields is certainly heavy.

One of the key reasons I think that Antichrist Superstar was so sucessful was the role Trent Reznor played in the production of that album. I think Marilyns vocals kind of took it too another level though.
