> your own music taste determines what you think constitutes good music taste

No, your own music taste determines what you think is good music. Taste is not about holding your own opinion higher than others', it's just about what you like or not.

I still find it weird that it's a 50/50 split though. Maybe a lot of people aren't thinking so much about whose taste is better, but whose is more refined? Like how people who aren't into wine might not take their own lived experience as seriously as the words of an experienced sommelier?
