What is "pure music"? Who listens to music with no ideas about it?

Of course music can be worse than random: it can be annoying.

I get a downvote, huh? Look, I like Ornette Coleman. I like Nurse With Wound and Merzbow and avant-garde noise. I do not like 21st century pop. If I have to have music played to me against my will, I would way prefer it to be random notes than if it presented a slimy modern personality, or used a tone of voice to sing at me with, or conveyed vapid little bad ideas in its lyrics.
