If I pay $10 and listen to 50 tracks, I want $10 (minus the provides fee) to be split among precisely those 50 tracks.
The difference is if you only listed to 50 tracks your listens are worth more that someone that diluted their listens over 5000.
Throwing everyone's fees into one big vat and dividing that according to the total listens, is bullshit. I want my favorite artist to be paid by me and I don't want to subsidize the worlds most popular artists that I never listen to.
