I'll have to disagree with you about Metallica, I believe that their first four albums, five if you include Garage Days are wonderful. After Justice, I think that the band members were replaced by replicants or underwent some kind of brain wiping, it's quite sad really. Also I have to agree with Al, no Iron Maiden and no f@cking Motörhead, tsk,tsk,tsk. BTW, I was/am a big fan of Thrash, besides the bands you mentioned, I love D.R.I., Suicidal Tendencies, S.O.D., Overkill and many more. Also love the Misfits, Samhain, Danzig, Black Flag, the Dead Kennedys, Ministry, etc.
