Ps - I kept it metal because all the non-metal stuff I really like was released before I was born. I also find that I can listen to a metal album (of a band I like) all the way through and like just about every song...that's not the case for bands I like in other genres imo. And you old farts will have a longer list and probably more non-metal artists/ albums in it as well!

1986: Metallica - Master of Puppets, Slayer - Reign in Blood
1987: Death Angel - The Ultra-Violence
