I have discovered that I like this album more once I deleted "Crazy Tonight", "Stand up Comedy", and "Take off your Boots" from my playlist. The whole thing flows better, and without those tracks it's still longer than many classic rock albums, so good enough. And yes I think "Winter" would have worked well in this context, which makes the album darker, deeper, and more cerebral in feeling and mood, which is probably what they were going for, generally speaking. The kernel of a great U2 album is there in NLOTH, but somehow it doesn't go far enough in any one direction to really impress me (that is, by U2's enormous standards).
"Magnificent" and "Cedars of Lebanon" are the two most fully-realized tracks, I think. I don't think they could possibly sound any better than they do. "Cedars" is actually my favorite track on the whole LP, which is a bit odd. This kind of Cohen-esque character study I found very successful (unlike some of the hyper lyrical pretensions of, say, "Breathe"). "Magnificent" is sort of a classic U2-sound, but it's so good it just works.
Definitely would be a good move by the band to get out another piece of plastic very soon, though, I think.
