Jonathan Mayhew has some sharp thoughts about "taste" here:

The mystery of taste is not why we don't like the same things, but why we ever correspond at all. If taste is subjective, then there's no reason two people would ever agree. So there has to be something in the object itself. It's not just that we like Mozart because we're told it's supposed to be great: the response is genuine.

This reminded me of some claims I made in an essay I think I have linked to before:

Taste is not an individual matter; the idea that "there's no arguing about taste" is backwards: there is only arguing about taste. In fact, tastes are the communal result of argument: our "individual" tastes only develop within a context of differing tastes in which each of us confronts others with our response to works.
