The endless questions are implied anyway as the borders are not very clean. 12 tone jazz still popular music are already serious business? Neo-Classic-Metal? etc ;-)
Yeah, but the average person doesn't know what dodecaphonic jazz is or where exactly the line blurs between u-musik and formal music :p I don't think it's even possible to explain that to a person who hasn't studied music at some point. They just lash out at me whenever I mention something they aren't familiar with, like you see in this thread.
