I think there's a big difference in a list that represents 'influential' acts and a list that's just stating who were the most popular bands in stages over a 30 year span.

Slayer's Reign in Blood and Pantera's Vulgar...are the absolute apex in thrash but no mention.

Faith No More and their innovative rap/jazz/thrash fusion style must be the biggest influence on 'nu metal'.

Green Day are constantly copied and, although pure shite now, when Dookie came out they were a really interesting good band.

Swap Ozzy for Sabbath.

What about being daring enough to include less popular but more influential bands. Napalm Death? Marilyn Manson? Sonic Youth? Incubus?

Green Day blew up big but I'm not sure if I'd call them influential considering the majority of the well known pop punk bands were playing shows/releasing records at the same time and had been since the late 80s. The whole "Pretty Fly For A White Guy" era Offspring made more of a mark on the modern bands like Good Charlotte IMO.

With you on the Faith No More influence on nu-metal. Rage Against The Machine played a big part in that too.

It gets quite complicated once you delve into it :D
