Music is like everything else - 90% fashion and style, and following what others tell you would be "ca craze". There's even a whole philosophy built around this - postmodernism is mainly swallowed by people who need an excuse for not having an own opinion and wanting to be seen as "da craze" still.
There was a revolution, in that we nearly all can make and share music. That's a great thing
I still buy CDs, by the way. And second hand long players. And I'm happy music in the internet exists.
