Metallica is the best Heavy Metal band ever. No one can duplicate their sound or their speed(without sounding horrible/ like Slayer)and not to mention their album sales. You would be hard pressed to find a Heavy Metal band that has stayed relevent for twenty plus years like they have, as a matter of fact Metallica is the only Heavy Metal band that has done so. If you ever see these guys live, the first time I saw them was in 1988 on Van Halen's Monsters of Rock Tour, they were great and they play a wide variety of their catalog. I could care less about the Napster thing because I do not use any of those types of websites anyway. I do agree that their albums starting with Load are not anywhere as good as Kill 'Em All to the Black Album, but if they did not change a little, people would be saying that Metallica just keeps putting out the same sh*t. So that is a no win situation for them or any other band, and it is also a very weak argument to make. Metallica is the most influential Metal Band of all-time and most likely will be the only true metal band to be inducted to the Rock and Roll Hall of Fame in 2008 and on their first year of eligibility.
