I clicked the button. It's literally within a few percent of where it was 30 years ago, adjusted for inflation. I call that broadly in line. Yes, it was much bigger in 2000, and much smaller in 2010, also bigger in 1978 and smaller in 1982.

It was never that big, in absolute economic terms. I remember Slashdot was joking 20 years ago that one of the tech companies should just buy all of it to make the RIAA shut up. I guess it's unsurprising that organized culture has an outsized reach.
