Maybe all that's so, GtD, and I know exactly what you mean about the 'bleating', but I think we owe it to any artist to judge them on their own merits, and not be influenced by any family connections or whatever, difficult as that may be in practice.

It does make me laugh too sometimes, when (say) the son of a rock star - who probably only got a recording contract in the first place because of his famous parent - whinges about his music not being 'taken seriously', and that they got where they are through their own talent without any help from their parents, etc. etc. - but I still think we should try to ignore that when judging if their music is any good or not.
