It's arguable, Definitely.
But then again, A world is nothing without its art and music. Specially music.
They're important forms of expression to humans, Even as 'valueless' as it might seem at first. Yet we all seem to give our different values to everything that happens in our world, Anyways. Hence why it's so arguable in my opinion.
The Punk movement of 70's New York and why it exists is a huge example.
