I don't know if they're higher administrative costs, but it requires more trust in Spotify. In the constant stream revenue model, you take the total revenue Spotify is paying out to artists, and divide it by the total number of streams, and that's the cost per stream. Multiply that by the number of streams an artist had, and that's how much money they get. You only have to trust three numbers from Spotify, and two of them are global numbers, so other people will look into them. In the stream cost per user revenue model, you do that _for each user_, and then sum up each artist's revenue. That's a whole lot of math to be done. Now, computers can do that, but auditing this will be far more complicated.
