Further thoughts - I think you are confusing art, which is what music is, with a moral message.
The entire raison d'etre of popular music is to bind together one generation who love not only its joy and passion, but the seriously negative effect it has on the previous generation!
You cannot conceive of dishing out artistic freedom on the basis of some kind of lofty moral code. Whom pray polices this new world - who decides who is 'moral' enough to receive the right to create their art? It is a concept that borders on nazi thinking, i am surfe if you think it through you will realise that if you apply this 'logic' to a pop star, you will have to do it to all art forms. Where then?
Will Frederick Forysth be banned from writing because he has right-wing views? Will Salman Rushdie's fatwa be applauded and encouraged? Where on earth does this concept end?
Fortunately, the presence of art in our world is not governed by the perceived moral correctness of the artists who may or may not be given an opportunity to bring their art to the masses, dependent on the type of lifestyle they lead.
God forbid that it should ever be so.
