It's gonna change again, I'm sure. Music genres will come and go. Right now it seems house and other electronic genres are mostly listened to. A few years ago the charts were still filled with RnB songs (gosh, I miss those days). But it's only a matter of time until it all will change again and maybe much more people will appreciate this good old 70s music again :) I will definitely try to teach my kids the values of such music one day.
