Especially the last two closing tracks, "Finality" and "Alternate Ending". Best closing to an album I've heard, and I can honestly say no songs have ever evoked such emotion as these two.
It... IS, but it's also kinda dull, y'know? I feel bad for that because there are tons of non-metal albums that are oppressively negative, but in Godspeed's case listening to it is kind of a chore. Oh yeah, I forgot about Shining - VII: Född förlorare, although I'm kinda on the fence if it's their most outright negative album. Also Wound Upon Wound - s/t, black/doom from Ireland I pimped earlier this year that blew my asshole apart. Almost harrowing at times, way worth the listen, and it's all free on bandcamp: http://wounduponwound.bandcamp.com/
This version of this track has always been by far the one song they released drenched in the most negativity for me.
YES! Breach is fucking killer and never get mentioned around here. I guess they're considered metalcore, but more in the Converge sense than some cheesy band like God Forbid. Converge has some albums that definitely fall into category of 'most negative' albums... They're another band I never see mentioned here.
Woods of Ypres do have some rather cheesy moments (particularly on the third album,) but it's primarily the good type of cheese and, at least for me, doesn't really detract from the music at all. I've just always enjoyed David Gold's approach. I can understand how it wouldn't appeal to everyone, though. As for Warning's Watching from a Distance, I've always found that to be quite a positive album. It's coming from a dark place, but I've always thought it was always looking towards the light. These are the albums that fit the bill for me: Ataraxie - Slow Transcending Agony Austere - To Lay Like Old Ashes Doom:VS - Aeternum Vale Make a Change... Kill Yourself - Make a Change... Kill Yourself Mournful Congregation - The Monad Of Creation Remembrance - Frail Visions Shining - IV - The Eerie Cold Sterbend - Dwelling Lifeless Xasthur - To Violate the Oblivious Strapping Young Lad have plenty of negative songs, but they're spread across the first 4 albums. If they were all on one album, I think that would be at the top of the 'wanting everything and everyone to die' ranks.
I'd like to point out that (although some AWESOME suggestions are here), "negative" doesn't always mean "depressing". You can also have pure misanthropy, like in the sludge/post albums that are floating around on here. A few more submissions: Rotten Sound - Cycles Khanate - Things Viral Elitist - Fear in a Handful of Dust Swarm of the Lotus - When White Becomes Black SotL is just shredding my eardrums right now. Definitely love bands where it almost sounds painful for the vocalist to get through each track.
Love Sex Machine. It's like Black Sheep Wall without the bass drops and more "distant" vox. Perfect for me right now.
I dunno, I think pretty much anything Swans fits. The Seer is a rough damn album and that just came out last year.
