In my opinion, which I think mirror's bobcflatpicker's comments, is there is a point with any type of music where the cleverness of the music outruns the general public's ability to enjoy it and follow it.
my wife used to describe this phenomenon as "the emperor's new music"
(If you aren't familiar with the classic tale of the emperor's new clothes, you won't catch her meaning)
another description might be "institutionalized crap" meaning something the elitists have blessed, and therefore anybody who doesn't like it must be neanderthal, so nobody will speak their true opinion.
My summary is that if an artist's main goal is to be "different", then anything goes, and the public may not like it. But if the artist's goal is to rediscover beauty in a new way, it seems that everybody in every culture embraces beauty.
