That's a cool paper, thanks for linking to it. I'm not quite sure how to make sense of all its findings. It seems to be saying: 1) If you aren't selling digitally, piracy can hurt your album sales (if your music becomes well-known enough). 2) If you are selling digitally, piracy doesn't really hurt your digital sales, as the piracy will generally be from people who wouldn't otherwise sell your music. 3) Making your music available on streaming sites has a measurable but very small positive effect on digital sales. However, it's unclear if they're trying to measure the people that would buy digitally if they weren't streaming, but don't since they can stream. (This my reason for being interested in jango/pandora but not spotify - on jango/pandora, the stream is presented to the consumer but not on-demand, so if the consumer wants to hear it again, they can't just stream it again like on spotify. So they'll still have an incentive to buy.) 4) Streaming might not have a positive impact on physical sales, although this might be because they're assuming that songs are digitally available.
