What is "good" music?

Exaggeration to prove a point.

Actually, no point. You are just exploiting the fact that almost nobody prefers a half assed MS Paint drawing before a fine drawing almost identical to reality.

A majority of people can think the same, but that doesn't make it better. Imagine that, in a close future, People see realistic drawings like that like a waste of time, because we have photographs, and everyone loves Half assed MS Paint drawings, because they don't exist in reality, and it's a fresh change. Is your pomegranatety drawing then a piece of art bigger than Leonardo's?

Southperry policy is to ignore reality in favour of weak rationalizations. Therefore, good means whatever they think is good must be truly good.

Still waiting your true answer.
