I agree with what you say. However, I think that I can speculate on the type of music that will endure 100 years from now. It will be the music that ennobles and uplifts. It will be the music that inspires. It will be the music that is recognizable and coherent (that doesn't mean dull). The screeching heavy metal sound may be fun for a while, and it may get you fired up, but that kind of thing just can't last. And the "kill the cops, f**k the hoes" variety will definitely not last.

There's plenty of such music in the rock paradigm. Rush, for example. It's possible that speed metal per se will not be one of the genres that survives.

Like I said it's awfully hard to predict what in the arts will end up retaining popularity in the future.

It will all depend, as it does now, on where you live, your education, and social position. It may surprise you to know that the majority of people in the world have never heard of the great classical composers or their compositions.

Believe it or not, they are not all barbarians. Knowledge of classical music isn't required in order to be a good person.
