I'm suspicious of anyone who doesn't regularly listen to music, in a similar way that I'm suspicious of people who throw household pets into boiling water. These people have something intensely wrong with them. I'm also at a point in my life which is linked to the vast majority of music purchases. It is not unusual for a person who enjoys a certain thing to expect others to share the same interest. But it can't be that simple.
Music is something unique.
I don't understand how it began, and I don't understand its near-universal appeal to billions of human beings. It seems to fill a need, perhaps one that was created with the conscious mind. Whether it came from development and evolution, animal instinct, or the indefinable something that makes up the human soul, I could never say. What I can say is those people I have met who do not regularly listen to music, regardless of the form, tend toward the uninteresting. They seem to have little to say.
