How is it that Coheed and Cambria is the only metal thing that has been mentioned in this thread at this point?

Wintersun, Opeth, Ensiferum, Chthonic, Gorgoroth, Emperor, Burzum, all epic bands with countless epic songs.

My favorites would be (prepare for a longish list)
Det Som En Gang Var - Burzum
Quasi Putrefication - Chthonic
The Drapery Falls - Opeth
When - Opeth
World to Win - Gorgoroth
Gorgoroth - Gorgoroth
Profetens Åpenbaring - Gorgoroth
With Strength I Burn - Emperor
I am the Black Wizards - Emperor
Veils - Ludicra
Battle Song - Ensiferum
Windrider - Ensiferum
Goblin's Dance - Ensiferum
Sword Dance - Ensiferum
Winter Madness - Wintersun
Beyond the Dark Sun - Wintersun
Carpathian Mystersies - Nokturnal Mortum

And lots others I can't be assed to list.
