Boots has deeper lyrics (about women) than I think you give it credit. as for the worst song, not only are you wrong about Boots being the worst, this entire idea needs to be titled, "the A Man and a Woman thread." easily the worst song they've done (the album version....acoustic was tolerable).
Album version of Miami is a close second.
Unknown Caller is the coolest song on NLOTH. Great lyrics with a spiritual yet modern-day application. and it builds in a really cool way.
