By "active listening" I mean listening to music without doing anything else, no reading or working or talking.
I find that I rarely do any active listening these days. I used to do it when I was much younger.
Do you do it? More or less than when you were younger? If it changed, why do you think it did?
I'm just reading a collection of essays by William Gibson (Distrust That Particular Flavor), and the very latest bit I read today was about how Gibson really don't care about the fidelity of the equipment and channel by which he listens to music, he thinks the music is there even by the worst channel.
I think there's a danger of "knowing too much" for enjoyment of something. For example, because I photograph, I notice if the highlights are blown in a photo, and it may spoil the enjoyment for me. But for somebody who know nothing about the technical aspects, it may be a wonderful picture which he gets great enjoyment from.
