I like to tell my music cynic friends that some of the best music ever made has been made in the last 10 years mostly by people you have never heard of in bedrooms and garages of all sorts. Much of it is made by indie artists without major financial backing but with relatively inexpensive and easy access to world wide third party distribution. This explains why Spotify and Apple are growing.
Sure there is a lot of mediocre music in all genres, but that has always been the case. The difference is now the people don’t need a middleman (corporate terrestrial or satellite radio) with all inherent middleman bias as a gatekeeper. If you look yourself you WILL find treasures.
