The proposition in the article only works because users pay a fixed monthly rate for unlimited listening, rather than a charge that is metered based on how much they stream.
Jack Stratton's proposition is wagered on the proposition that the users who listen to his tracks are ones who don't listen to very much other stuff. His listeners pay $9.99 per months, but don't stream very much, and a big chunk of what they do stream is Stratton's material. He doesn't want most of that $9.99 going to those other damn artists, who are just random junk whose material isn't sought out by anyone, but streamed randomly in Yoga classes, elevators, supermarkets or wherever.
If there is some user who paid $9.99, 70% of which is $7 going to the artists, and half of what that user listened to was Stratton's tracks, Stratton wants $3.50 for that month, for that user alone. Add to that other similar users, and extrapolate to twelve months and you have some non-negligible cash at the end of the year: better than a fraction of a cent.
Problem is, no matter how you slice the pie, it is a zero-sum game. There is so much revenue and so many artists.
Most artists, likely including Stratton, will lose this zero-sum game no matter how the pie is carved.
There is little difference between 99% of the artists getting peanuts, and 100% of the artists getting peanuts. The proposed rule would just create a tiny group which gets quite a lot more revenue than the rest, at the cost of slightly impoverishing every member of the remaining group, who then gets a slightly smaller fraction of a cent.
It's actually a good rule from Spotify's POV because this tiny group would represent "success stories" which Spotify could use for promotion.
On a different topic, this kind of reminds me of the whiners who complain about online dating sites. "I'm obviously a more qualified bachelor than most of the losers who make profiles on this site, so if only the implementation of the site were based on somewhat different rules, then I would easily get replies from the women I'm interested in. I might have found a girlfriend long ago if it weren't for this damn dating site. Waaaah ... sniff!"
