What is "good" music?

Is the red I see the same red you see? Does our brain see the colors the same way?

If we're both looking at the same red then yes, it is the same on a universal level. Whether or not we both perceive it the same is irrelevant to the bottom line. But that's the point, good is good as bad is bad. Whether or not I enjoy something doesn't make it good, it just makes it enjoyable to me.
