Wow, I can't believe I fucking missed this thread, being the Death caboholic here.
I like the new album, but I agree, Plans was better and Transatlanticism was fucking phenomenal IMO. The only three tracks I listen to on Narrow Stairs are I Will Possess Your Heart, Pity and Fear, and Cath..., which is a throwback song in style if I ever heard one.
Favorite Death Cab song? Without a doubt, We Looked Like Giants. It could probably be a qualifier for most depressing Death Cab song too, although I think What Sarah Said pretty much wins that contest.
