I know I'm late to the party, but definitely the A nightmare to remember part.
I just couldn't believe it, and I checked out of DT for a long while afterward before coming back around. My interest in the band was kind of waning at the point that black clouds came out anyway, but then I was like oh man.
And Its a shame, because I do love a lot of A nightmare to remember, especially the chill, slower part. There's an awesome song held hostage by the poorer parts. But oh well.
