having said all that, I believe Ian Anderson has a genuine love of roots and world music, and is not in the business purely for commercial gain, however he does have to sell copies, so he has to feature that which whill sell copies, and the sad fact is that being young and sexy will do this. however it means, as with tin pan aley and pop music that Music is not being promoted solely on its merit.
The only form of music [imo] which this does not happen very much is Clssical Music.
