I should offer my own counterpoint here. That analysis ignores the question of whether Pandora plays "rob" from anything else. But since Pandora songs aren't available upon request, it doesn't rob album sales. It's basically gravy.

Now, someone who makes a lot of money off of radio plays, and sees radio plays shrink as Pandora plays increase, they might still feel they have a beef due to the lower songwriter royalty rates.

Spotify, on the other hand, is different. Spotify does rob album sales.
