It's a tough question, I mostly see this album as one entity. Although I like it a lot I sometimes have troubles figuring out which section is from which song. Actually I really like every single song on it, a thing I can't say about many DT albums. Very consistent on a high level, but no real career-defining highlights. I guess i'll go with ITNOG, and follow the majority. If Vacant and SoC were combined in a suite, it probably got my vote.
