I've heard of Anthrax before, but I've never heard their music I think. Anyway, my point was that Metallica are a lot more famous in the mainstream than Anthrax (I don't think Anthrax were ever on MTV Legends for example) and that it's funny that you describe the more famous of the two in more words than the less famous.
Oh, I forgot to mention that I really like the songwriting of Robert Stjärnstrom of Machinae Supremacy.
