I fear it's pandemic right across the fine arts, Errikos. Over the past 100 or so years in particular, P.R. - i.e. what used to be called propaganda - has become virtually ubiquitous and omnipotent such that now it has seduced, suborned and saddled far too many people in western societies with the appalling belief that individuality - indeed one might say the soul itself - is something from outside, not within.
In the following dramatisation of the first rehearsal of Beethoven's Eroica, some important words are ascribed to Joseph Haydn, who attended the rehearsal. (play pointer set to that moment, 1:17:42, in this link)
"He's done something no other composer has attempted: he's placed himself at the centre of his work. He gives us a glimpse into his soul."
Thus began the romantic period in orchestral music.
Today, when the technical means of producing music have become so widely available, convient and affordable, I'm constantly reminded of Kierkegaard's bleak observation on the spread of printing technology, which he regarded as a somewhat comical invention, for:-
"Since when, oh God, have there been so many people with something to say?"
One thing surely has become horribly clear to many if not most of us today. The vast armies of people engaged, professionally or not, in producing P.R. for this, that and the other - and I include "corporate music" and all other kitsch music as part of their productions - are far from being those "with something to say".
