Shall I make a list? I'll try to limit myself to one song per band..
Opeth - Demon of the Fall, Funeral Portrait, When, the Moor, the Baying of the Hounds, Serinity Painted Death, I should just stop here or I'll just list their entire catalog..
Lamb of God - Ruin, 11th hour, Laid to Rest
Strapping Young Lad - AAA, Detox, Love, Shitstorm
Slayer - Die by the Sword, Blood Red, Raining Blood
Pantera - Domination, Revolution is My Name
Meshuggah - Concatenation, New Millenium Cyanide Christ
them, and "Katatonia - Soil's Song" is currently stuck in my head
Ok, I know I totally ignored my original statement. Too bad.
