There are a couple of interesting thoughts in this eassy.
I would add that some of the devaluation also stems from the fact, that music is ubiquitous and devalued because the act of creating it has been so much simplified, that everyone with a computer and some software (and I’m guilty of adding to this!) can now create a professional sounding song in minutes. Which in and of itself is a good thing, but the result is more than we bargained for so to speak.
