in practice will just give more money to the very popular bands since they dominate the market and leave a much smaller share for the others.Which is exactly the current situation, by the way. Anyway, what I was doing was just demonstrating that the system is not the same.
Although I am admittedly bad at maths and statistics, it seems to me that the system I am proposing would be more likely to pay out at least coffee change to small-time artists. I might be wrong, though.
Basically I think it's unfair and unintuitive how everything I pay goes to artists I don't listen to. There has to be a better system.
