THEY OPENED MY MIND MAN!
This album introduced me to what music really is, as well as the greatest song ever written.
This album is in my top 5 because my mom threw it away because of fears it was demonized.
Reign in Blood
My first taste of thrash from a good friend. Simply perfect.
This is an album where every song is great, this is probably the best album to come out of Canada. Period. I can't say much for their later stuff but this is good music.
This is on the list because it's rocks. It's the best album so far this millennium.
