I'm bored, so I'm doing this. My technique involves going to the page of every thrash band I've listened to, pulling out their top three albums that I'd rate over 8.5/10 (if there are three) and placing them in the list.

1.Megadeth - Rust In Peace

2.Coroner - No More Color

3.Coroner - Mental Vortex

4.Toxik - Think This

5.Slayer - Reign In Blood
