Very interesting report, and am not discounting it, but another factor is that maybe the pricing affect is already baked in from years of piracy. For example, back in the early 2000's, when P2P file sharing was being used to download music, then to compete, the music industry had to resort to iTunes store, which allowed users to buy just one song for a dollar, instead of the entire album (and then later on, to music streaming services). The damage was done decades ago, and eventhough P2P file sharing isn't big today, it's effects are still with us today (no music executive is going to go back to forcing people to buy an entire album to get just one or two songs).

But, maybe this report is taking this into account too??
