If the pot size stays the same, you are just shuffling around between artists. So artists who are listened to by people who only listen to a bit of music benefit, and those listened to by people who listen to a lot of music get less.

I guess there are two groups of people who listen to a lot of music:

1) young people

2) people who like music a lot.

So bad news for Taylor Swift AND obscure bands only interesting to enthusiasts. Not sure that's better overall. I would prefer a system that is regressive, that pays more for the first 1k listens than the last 1k - but that's definitely not fair :)
