You seem to be implying partially that it's about which style of music to play. That is not what I mean, although I do like or not like certain styles. I think that people who don't care much about music either way (who are responsible for most bad music) are easily convinced of something better. A famous example of great taste in music is John Peel. He could figure out what people would eventually like because he just knew it was good. AFAICT he wasn't just trying to predict what would sell best in the near future, he just trusted his taste. Taste isn't 100% subjective - otherwise what's the point of ratings? This discussion comes up on sites such as this regularly and I'm on the side that good and bad art exists. I don't think it is worth rehashing that discussion, if we disagree we should just agree to disagree.
