So, what you and the author are claiming is that the music is bereft of any marginal value, but musicians make their money selling a unique experience (a live concert) or trademarked goods which have value only because of the band or song trademarked and used on the goods. Would you then not call the music a good of a higher order? Because in order to make the other products, you need the input of the song or band. You could not sell the other goods without the input of the music.

BTW, perhaps Queen Taylor now has earned a reverse Midas touch, everything she touches turns to sh*t.
