Is it possible to quantify these changes in some way?

People say musicians always made a pittance, has that substantially changed in the past 20 years?

Labels seem to be buying up old catalogs, so there's some truth in that.

His point about platforms not being effective in breaking new artists seems right though. I remember an article where Grizzly Bear was quoted as saying that without Radio play, you seem to hit a ceiling in terms of building a large, permanent fanbase.

My personal suspicion is that without repeated exposure to new music, done semi-forcefully through radio, it becomes much much harder and expensive to break new artists.
