I have an 11 year old, and many friends with tweens, teens--I see how kids view entertainment, etc. etc. these days. As for bands and rock music, they're generally kind of "meh" about it. Heck even with the millennials, being in a band is simply not perceived to be particularly cool anymore.
I don't have kids, but that's what I've perceived, too. Music in general seems to be quite disposable for a lot of them.
