I think the acts are an irrelevance, because despite the crap in the media about them being "important", you and I have seen plenty of these acts come and go. They are transient and will soon be gone. They will go - and so will their "values" - because, in fact, they do not have any real values at all. It is just a promotion gimmick. Time is much crueller to them than we could ever be. Real artists can look back and feel they have done something with their youth. I found Joni Mitchell very sexy back in the seventies. There was real substance there too. The current crop of airheads will come and go just as they did in any age. We do not need to "do anything about it". Time will fix it just fine! Most of our youngsters will grow up. There are people who sustain a sexual age of fifteen throughout their lives - but they are beyond help anyway.
