Well, I know many people disagree with me, but I find it very easy to distinguish between DT's albums. Whatever song of theirs I hear, I can immediately associate it to it's album.
I disagree. Damage done was much more mid-paced and not as fast, and Characater had that wall of sound, with everything going on at once. The only track I think that could be on DD is the last track on Character, which is reminiscent of Damage Done's sound and feel.
Haven is probably my least favorite DT album. It seems such a half assed album. Kinda like ReLoad to their Load (which is Projector, which is great).
