When I first read your comment about this scheme keeping money from artists I was skeptical. But, yup! It is right there on Spotify’s website:
We distribute the net revenue from Premium subscription fees and ads to rightsholders.
Now, granted a bunch of those “rightsholders” are likely big corporate record labels but your point stands. The little guy is getting screwed, too.
Though, adding to your final thought, I bet if it was only the little guy getting screwed and not the corpos I bet DOJ wouldn’t have cared.
Pretty obscure term. Don’t beat yourself up.
