Hawkmoon is the second best song left. AIWIY is my second favorite U2 song overall though, so the competition is tough at the very top, pretty much impossible actually. Both songs exude passion with a dark romantic bent that sets them apart from most of U2's catalogue save WOWY and most of Achtung Baby. Hawkmoon in particular has a pretty unique conceit behind it; unrequited lust driven by absence (this being a road album, after all) and alcoholism. It's pretty depressing if you think about it. The live version makes it more obvious that the song's lyrics are extremely sexual and slightly pathetic. If the slide guitar intro had made it into the song, it would be top 10 for me.
