I'm inclined to agree with the author of the article. Personally, I think 90%, if not more, of today's modern classical music is pretty much worthless and a paying customer definitely has the right to express their approval or disapproval within reason. However, many works now considered masterpieces now were poorly received initially (Stravinsky's Rite of Spring comes to mind). In the end, the true arbiter of the quality of one's work is the test of time.
