Well, maybe; but since one person's music is another person's noise, it may be just as appropriate to say that each new genre builds another bridge, erects another border, and creates another subculture. No?
It's all about how you perceive the music since it really is all about taste. What I call music, some might hear it as something completely different.
Depends on the music. My parents hated most of the 60’s and 70’s music that we as kids loved.
