@IAmEternal: \m/ WEAKLING!! \m/
I say My Arms, Your Hearse, definitely. This album rips out my fucking heart. I can't listen to it all the time, but when I have a crush on someone or something, or am otherwise feeling things strongly for whatever reason, this is the album I listen to. Maybe this isn't depression, more like raw cathartic power, but when I think 'depressing', I think Katatonia much more than Opeth. I guess Morningrise is in second place here, for the song The Night And The Silent Water. I get chills with this song. So, MAYH, then M.
