While I agree that there is always good music around, it doesn't mean that the amount of good music around is always the same. Of course there were flops in the 80s and 90s, but can you name 5 world-famous bands that make good music now? Good music doesn't come from just a bunch of people picking up guitars and playing some notes, it comes from certain states of society as whole. Every major musical revolution was the birth product of an intellectual and cultural revolution in a society: Rock, Punk, even pop and rap.
