In a friendly way Mark....have a look at TV adverts aimed at kids ....THEN tell me TRUTHFULLY they do not buy overpriced crap. To a lesser degree the same applies to adults. Why should music be any different. It is a scientific fact that at least 10% of the population are tone deaf. After watching AI I maintain it is at least 99.9% but I also maintain that the general public with only a few exceptions have a narrow disposable taste in music caused by only listening to such a narrow mix being put in front of them by the media and pressure by their peers to blindly follow.
As a famous showman once said "There is a sucker born every minute"

The more sheep the more BAAAAs.....

PS Nobody will admit that they are easily lead....but we all are. Why do you think politicians get elected.
