I think music like every art form is changing according to its role in society ("society" in a broad meaning included economy obviously). So there is a long term perspective, an historic one, and short term perspective, personal one. Just like radio broadcasting or recording changed the way music was listenend and its place society, its social importance, it audience, etc., so computer and internet did. It would be more interesting a serious social and economic surveys from scholars about what music is now in a specific contest, I suspect India and Northern Europe have quite different approach toward music. The relation between sellers, music industry in a broad meaning, musicians, producers, record companies ecc, and buyers is worth of an investigation too. What appears obvious to me, in my personal short term perspective, is that for decades music was THE THING, it goes with social changes like the anthem, from Presley, Coltrane, Dylan, Tupac, whoever you like, it was a flag of membership of social groups, now, with social medias is just ONE OF THE THINGS. I hope my english is enough good to make clear my points.
