No, the issue is that it's noise salad not music. To bring any other rhetoric into it is mere obfuscation. I'll bet you've got a tricky lawyer who can convince people that your noise is music, but that doesn't make it so. Fortunately, Mozart et al didn't need tricky lawyers to try and convince audiences that theirs was music and not sound effects or noise. But then, they didn't have circular saws or helicopters back then.
Yes, you can certainly hear tones in certain noises. But tones, by themselves, do not music make. I'm surprised you haven't figured that out with your interest in the composers from the ancient world you say you listen to. And it's also certain that music, as I understand it, reached a tipping point with nowhere to go. The answer isn't noise, but there are some wonderful new composers around like Brett Deans, just to name one, who write very approachable contemporary music. He's a conservatory graduate and virtuosic musician and his music reflects that rigour and discipline.
I'll continue to listen to contemporary orchestral music, or Xenakis' "Rebonds", for example, because it is more than just tonal salad or noise salad and certainly not the industrial variety of noise some tiny percentage of the population deems is music. Apart from the obvious academic musical discipline involved, there is a generally accepted consensus in this world about what words mean, what a film is, what a poem is and what constitutes music. I go along with all of that because nothing has come along to convince me I'm wrong. Like yourself, I enjoy music from plainchant up to the present day. I draw the line at noise because there is such an abundance of non-noise I just don't have the time. And, frankly, I don't need to align myself with some tiny, misunderstood but pretentious clique of avant gardists because I want to identify with them and feel important or superior to the rabble who understand Bach. I don't say this is you, but I sure identify these kinds of motivations in some cultural avant-garde cliques, eg. Andy Warhole, the 'beat' generation etc. Ephemera 101.
And I certainly wouldn't reply upon some postmodern re-evaluation of a definition of music so that I could wedge my preferences into that tiny apperture.
You like it. Good for you, but don't expect us to fall into line and cheer along with you.
