What do you mean by "trouble?" Financially they're making more money now than they did ten years ago thanks to streaming royalties. Record labels make no direct money from radio airplay. So they focus all their attention getting their music made and placed on streaming services. The problem is they have to find a way to push people to that music, and radio can do that. So the end result is you have some artists (the ones who get airplay) making a disproportionate amount of money, compared to those who don't get airplay.
Here's a look at the music industry over 40 years:

And according to your link, the music industry are presently making less than half of what they made in 2000 (they were making twice as much in 1977) which is part of my point. Any industry that is making less than half the money it made just 20 years ago is in trouble.
