My husband is a U2 fan and over the years he has won me over to an appreciation for this band and it's earnest attempts in song to call out out our soul's need. (And he has taken me to some amazing concerts.)
I think the band does a good job writing on the state of the soul, and their lyrics are full of aching and poignant themes that make a person question, as they should, what is down deep. I do wish they were less cagey about sharing the Answer at times. But for what it's worth, in this interview, with all of it's modern-day cliches (when in Rome...), Bono does just that, expressly.
