This sounds very much like everyone does not want artists to get better payouts. (At least not all artists.)
If more than 50% of what listeners end up paying for the subscription goes to the artists, I guess they'd prefer that, rather than the money going elsewhere.
Netflix was the first ever streaming service I canceled the subscription without feeling I had lost anything, after more than 10 years as a paying subscriber their quality declined so much I didn't care about it at all. It's been 3 years and I never thought about subscribing again.
Where did you get this arbitrary number from?
And no, it doesn’t look like everyone wants artists to be paid more. What everyone wants is cheap access to a large catalog.
