wow, so many beautiful lyrics to choose from. and i can relate to a good number of them.
i've gotta go with let down. i've been in two relationships where i was ready to give my all to the girl, but in the first case she was not prepared to do the same at all, and in the second case, we had terrible misunderstandings and i wasn't given a second chance (i'm still trying to this day, the relationship ended about a month and a half ago). the lyrics and performance of let down, especially the acoustic performance in 2005, almost always get to me.
close alternatives include: crawl back in, too late, condemned, into you, and in the darkness.
damn, such a great album. it's a shame that it was so quickly forgotten in this community.
