New music is dying. Seriously, how do you improve on what has already been recorded?
There was a lot of great music made in the 70s that was unknown then, that is being discovered now by new generations.
Thanks to online resources like Youtube and Rate Your Music (which, among other things, publishes the top 1,000 songs for each year going back to the early twentieth century), I have discovered hundreds of popular songs from the 1910s-1980s that I never knew existed.
