My vote? Noise, not music.

I've heard the same thing said about EDM, dubstep, metal, alt rock, rap, punk, pop, rock, and rock and roll.

The truth is, any time you try to draw a bright line between what is and isn't a form of art, someone will try to bisect the line in hopes of creating something new and interesting.

I think when teenagers' music starts to sound like noise to me, it just means I'm getting old.
