While I completely understand this is a U2 forum, I don't think there is any denying that Coldplay is a much more important band for people my age (mid-20's) than U2 is.
I don't know a single person my age or younger who listens to U2. That's not meant as any sort of insult, or argument of musical quality...all I believe is that it's a generational thing.
People who grow up with one band always think that bands that come afterwards are crappy, or inferior by default. I don't think that's necessarily the case, it's all subjective in the end.
