Hi everyone. Just went back and read through about two weeks' worth of posts. Nice to catch up, and I'm enjoying all the discussion.
Gonna weigh in on the whole U2 appealing to the youth topic.
My take, as a middle school teacher, is that most of my students don't listen to much music at all. They aren't music fans who sit in their rooms and listen to albums the way many of us did growing up. Their knowledge of music is not deep. The boys might listen to hip hop, and the girls wear Bieber and boy band shirts (generalizing here; there are exceptions). It's the rare kid who listens to a band not easily found on the radio. At the beginning of the school year, I asked my students to name their favorite band or singer. Most said they didn't have one, and few could even tell me what they listen to at all, let alone music they're passionate about.
That said, I do play U2 in the classroom. The kids will sometimes recognize a song like Beautiful Day, but not know who sings it. We watched The Blackout video, and the kids were into it. I've seen two kids with Joshua Tree shirts on this month, and the tour has yet to stop here, so that is promising. Those are kids whose parents listen to U2, and that's how they've seen the light.
Maybe the kids I'm talking about are younger than what y'all envision when you mention U2's missed opportunities at connecting to a younger audience. I honestly only see a limited opportunity anyway. My students are way more into YouTube and video games than music, which makes me sad.
