To that end, I found this blog post by NPR Music to be very interesting. The premise is that parents who are into their music should probably meet their teens halfway in terms of listening to and accepting the teens' music. Seek a common ground.
NPR wrote, "It's tempting to advise you to look for common ground in the form of contemporary bands who reflect the sounds, looks and values of late-'70s rock 'n' roll; those bands could then serve as gateways to more modern music you can enjoy together. But I've got a vastly better suggestion: Take turns sharing each other's music in each other's company. Go to concerts together, loan albums to each other, take car rides together in which you take turns playing songs for each other. Spend time together. Make music a mutual point of growth and bonding."
Sounds like a good idea.
