Thanks for all the suggestions so far. I'm in the process of trying to track some of these songs down. And Suicide, you weren't kidding about it being a *long* song
Incidently, just to throw in my own recommendation here...if anyone hasn't heard Anthrax since John replaced Joey on vocals, they sound much different (and IMO much better...John Bush has an amazing voice for metal). Out of lots of songs to choose from, I'd recommend "Inside Out". A great song, maybe not their best, but a good example of what kind of what they can do.
(If anyone wants to swap an MP3 or two, PM me)
