Those aren't even examples of taste though as much as idiosyncratic single-song ratings when the topic is about preferences for different tonal groups (consonance, dissonance, etc.). Unless there's a strong generalization possible for an entire genre based upon novel experiences (whether positively reinforcing or negatively doesn't matter here) I don't understand how taste is shaped so extensively in this manner.
