2. Slayer - Reign In Blood
No one has ever bettered the ferocity, pace, and unadulterated aggression of this album. Packing 10 songs into a mere 28 minutes, this CD leaves no room for taking a breather. This CD single-handedly changed the face of Thrash metal. Everything before this paled in comparison. Since this release, this is the benchmark that most any thrash oriented band will be held to. Plain and simple, this is the soundtrack for ripping your neighbors head off.
