I don't understand the argument about paying all artists a fixed amount per stream when customers aren't paying a fixed amount per stream in an unlimited subscription model. If I listen to artists X, Y and Z, it makes a lot more sense to me that the only people who get paid from my subscription money are artists X, Y and Z. As opposed to the situation we have now, where, as a sibling comment points out, if I never listen to Taylor Swift the largest portion of my subscription fee still goes to her.
