1. Guns N' Roses
2. Pink Floyd
3. Type O Negative
4. Lacuna Coil
5. Anathema
6. Opeth
7. Tool / A Perfect Circle
8. Black Sabbath
9. Down / Pantera
10. Black Label Society

Honestly, I am not even happy with this list because there ar emore that should be in there. Its tough. SO what are your favorites.
