I voted for folk, even tho I listen to all 3.
My favorites are
Korpiklaani,
Folkearth,
Ensiferum and Moonsorrow.
I also listen
Nokturnal Mortum occasionally.
Amon Amarth is classified as "melodic death" here in SoM, but I think their lyrics are close enough to match viking or
Pagan metal, like someone said before. Not to forget about Equilibrium.
Anyways, you guys have listed quite many bands I haven't even heard of before. I got to go do some research on all the names, I've spotted on your messages.
"When lights go Out, Malice grows in the corner, and eats it's children. Fear of death awakens, and gathers troops under your window. Fold your hands, so that devil won't snap your neck..."
