Technical Death Metal - Either Atheist (if they count) or Spawn of Possession.

Progressive Metal - I have no shame in electing Opeth

Death Metal - Morbid Angel, especially if the new album is even a bit better than Heretic

Black Metal - Hard. Going with Emperor or Dissection

Black/Death Metal - Dawn or Sacramentum

Power Metal - Demons and Wizards or Blind Guardian

I don't really listen to much of other genres, but I'll throw in these:

Melodic Death Metal - Kalmah

Depressive / Suicidal Black Metal - ColdWorld

Traditional - Judas Priest

Thrash - Metallica's First Four

Folk Metal - Ensiferum or Moonsorrow
