wow, there's truly many of them!
to start with some:
Eternal Tears of Sorrow: The 7th Eclipse (guitar intro, keyboard line, combination of key-background and shredding guitars, guitar solo and following rhythm line with guitar solo, etc... *hmmmmmm* )
Kalmah: Heritance of Berija (this *wee* of the guitar is great!
)
Kalmah: Hollow Heart (all =) )
The Black League: Bunker King (the whole song is one special "moment" from the heavy doomy intro, to the grooving stomping refrain, to the guitar solo ...)
Godgory: God's Punishment (the beginning and when he starts to sing the refrain with clear vocals)
Lux Occulta: Opening of 11th Sephirah (beginning, keyboards and when guitar solo starts)
Morgul - Black Hearts Domain (beginning and when the bass plays along with the violins and chello(s) )
Amortis - Dark Visions By Candlelight (when the acoustic guitar plays alone with the double bass drum - sort of tranquil solo)
Tenhi - Lauluni Sinulle (intro and when he sings, Finnish sounds.... sexy
)
Tenebrarum - Rites (combination of rhythmic violins and bass)
Susperia: I Am Pain (the little break after the intro and the following guitar, as well as the moment when the guitar solo is introduced. the solo itself sucks)
I hope, I could point out the important parts
