I wonder if a law enforcing more transparency couldn't help here. It is in the interest of the music labels and the streaming companies to maximise their profit, which means minimise the pay-out to the artists. Customers have to be very motivated to be able to make an informed decision. And most often they probably aren't really motivated and happily chose the cheaper option. But I have hope, if the impact of the customers choice on their favourite artists is directly visible, it will create more pressure to increase the payout. E.g. each time you listen the song on A, the artists gets X, if you buy the song the artists Y.
