It seems like this still conflates the quality of a person (objective) with the quality of one's music taste (subjective). Your example of quality (moral and rational, I assume) people loving Stockhausen and you not loving it informing your self-assessment only works if music taste is an objective good, like preferring non-murder to murder. Even then, we would need to know that preferring Stockhausen or non-murder is an objective good, since presumably preferring it is among the quality-making properties of your quality friends. So unless I can know which music is objectively good in a properly basic or evidential way, I'm stuck never knowing whether my music taste is good or bad. Or, as I think is the case, music taste is subjective.
