What's interesting to me about the music scene of today is how closely it now hews to a "long tail" model. The publishers have so much data about what streams, so the most popular stuff has become incredibly homogenous (not that pop music wasn't always in a pretty narrow groove). But at the same time, thanks to the proliferation of music production tools and channels to share it on, the long tail is filled with diverse and interesting stuff from every conceivable genre.
