Nothing against Hammett or Hetfield, but the opening riff on Metallica's "Four Horsemen" is serious head-banging stuff. It was also his song, but Metallica changed the lyrics after he left the band.
Or something like that. It's been far too many years. You know, maybe I'll head to iTunes...
You're right. It was originally called "Mechanix" and it appears on Megadeth's first album.
Hetfield's singing on 'Justice for All' made me a Metallica fan for life.' Ulrich's selfish whiny rant on Napster made me less so (yes I still listen to their stuff but I will never pay a dime for another one of their albums - not that I have much cause to).
