iTunes changed the music business into what it is today. The heyday of albums, bands, 20 dollar cds is over. But music has become less special less mainstream and people are less likely to identify themselves by subgroups formed around a music type. Young people are not on mass claiming to be Punks, goths, hippies, metal fans, disco heads, something new etc. Which has slowed down the evolution of music.
