Right on. The same thing happened to me with U2, Coldplay and Radiohead, and they are three of my top bands! Additionally, I understand that all three bands have mutual admiration for each other.
Expanding on what you wrote about liking the music after repeatedly listening, I have found that concentrating on the lyrics repeatedly reveals much more depth to what is written. Bono writes in so many metaphors, that sometimes I just listen to them without really understanding them. It's when I listen to understand them that makes it even more enjoyable.
Crumbs From Your Table is a perfect example, as it can be interpreted in multiple ways, but actually refers to Africa's plead for help. I remember listening to
So Cruel from
Achtung Baby for over a year before catching all of the subtle metaphors. Anyway, all that to say that I agree with you, Grandmaster, and I'm glad you're enjoying it!
