Just gimme whatever you like. I listen to every type of music, it doesnt matter if its Daft punk or if its Nirvana.
You asked for it...
Wintersun - great for the season - check out Death and the Healing, Sadness and Hate, Winter Madness
Amon Amarth - viking death metal! - check out anything from the album With Oden on Our Side
Finntroll - some fun Finnish folk metal - check out Trollhammern, Skogens Hamnd, Solsagen, Jaktens Tid
Korpiklaani - more Finnish folk metal - check out Wooden Pints, Midsummers Night, Happy Little Boozer (if you don't hum along to this...then I can't help you)
Ensiferum - pagan metal - check out From Afar, Battle Song, Iron
Eluveitie - pagan metal with a twist - check out Inis Mona, Rose for Epona (beautiful female lead vocals), Nil
Funeral Tears - funeral doom metal - all instruments played by one guy - check out Your Life My Death (hooked on this one)
Xasthur - depressive black metal (for very specific moods) - check out Prison of Mirrors, Walker of Dissonant Worlds (instrumental, but moving)
You can see where my tastes lie, and this is but a sample. If you happen to like any of these, I can offer more suggestions.
Enjoy
