“What sort of music do you like?” - a common question, often used to introduce and discover what one may or may not have in common with another. Along with “what do you do?” and “what are your favorite movies?”, musical preference is a typical icebreaker for people engaging in the never-ending game of social alliances and competition.
Yet many claim their musical identity is deeply personal - a piece of their soul, bared for those who share their tastes. There are movie buffs and foodies and other flavors of enthusiast, but love of music has a rare universality relative to other options in the buffet of life.
Or does it? The key word of our introductory question is not music, but sort - everyone cares about music, but everyone characterizes it quite differently. A lover of death metal may eschew country as “not real music”, and vice-versa.
