If you watch the video it's clear that the guy is not making a generalised statement about all contemporary music. He is making a statement about much of the production line chart filling dross that comes and goes with each week.
As someone who listens to a lot of new and emerging music I know there is a wealth of fantastic stuff out there that is relevant and has artistic merit. Every age has the same and you've always had to wade through crap to find the gold.
I hate the idea that the only music with any merit, the best stuff ever created just happens to be the music you liked in your teens and twenties. It's as stupid an idea as saying the religion one is born into has to be the only true one.
I agree with much of what the guy has to say but that is not the same as saying that all new music is crap.
