To answer the question ... I've no idea.
Boy: consistent throughout, and come on, THE ELECTRIC CO.!
October: I guess this may have the weakest second half. Then again ... Scarlet and October are gorgeous and I really enjoy With A Shout. To those of you who don't listen past October: what's wrong with Scarlet?
War: Great throughout, but Red Light drags the second half down a little, and I've never been overly enthused about THBAO.
UF: Perfection from start to finish.
JT: See UF.
RAH: The end is better.
Achtung: Despite the fact the second half has TTTYAATW, it's also got The Fly, Acrobat, and Love Is Blindness, three of Achtung's four classics (the other being UTEOTW). Second half is better.
Zooropa: Hmm. This may just be the winner. Then again, the first half has Babyface ...
Pop: Second half has Gone and Wake Up Dead Man. Definitely better.
ATYCLB: When I Look At The World and Grace are two of my favourite tracks. I think this album falls down a bit in the middle with In A Little While and Wild Honey, but I don't think the album's top-heavy.
HTDAAB: Brilliant from start to finish.
