> and gives 'em to the artist you've listened to the most

This seems like a way to sound popular without actually solving the problem. IT sounds like it would help "yay my favourite artist gets lots of money!" but when you model it out I'd expect quite similar outcomes – most of your money is still distributed in the way Spotify do, and often your top artist might still be one of the popular ones, and small artists aren't going to be the top of many people's listening.
