To put it on the flip side, contemporary art music has to fit within academia's notion of serious music. Which leads to a lot of music that nobody likes except music professors. Such that people's favorite "classical" music of the late 20th and 21st centuries tends to in fact be pop music (movie scores, video game themes, etc.).
Pop music is driven by the media. The media influences young people to listen to it because it's "cool". And it's all about money. Cash is king right? Make it young, make it hip, make it sexy, make it cool... but if it doesn't sound good... well... eh.. no big deal. They won't know the difference.
I don't listen to contemporary music either... but I do like all kinds of different music.
However, pop music grinds on me. It sounds
processed.. for lack of a better word.
... and I very rarely agree with what acedemics consider to be "good music".. however, I'm sure that there are those out there who probably are swayed by the acedemia. And you'd be correct, that is equally bad. However, perhaps, slightly more informed. Snobby, but informed.
