Two things:
(1) I am not surprised at all that people would try to make it look like Pandora is treating artists poorly and/or not paying them significant royalties.[^fn1]
(2) The real problem in the model is not Pandora, but the fact that the record company gets 50% of the royalty Pandora pays. *That* is what has to change in this new economy.
[^fn1]: It is especially laughable when standard radio stations pay nothing.
