I really think we should take a more lateral approach to this question. So far, everyone has assumed that it is the music "good" or otherwise that is fashionable, or not. The music is the symptom, not the disease. Young people, in my opinion, are guided mainly by their hormones, and the perpetrators of "pop" music are, on the whole, very attractive or charismatic individuals, who are managed by people who know how to sell it. As a youngster, if Paul McCartney had sung the alphabet, I would have bought it. Musical tastes vary, thank heaven, but the music isn't always the priority, it's the effect it has, and the money it can make. Hwyl, Bron.
