There's plenty of anecdotal evidence that the price of a song wants to be zero (labels complaining about "competing with free," file sharing, CD borrowing, etc.), but the topic had never become the focus of a paper written by an economist, to my knowledge anyway.
Will Page, who describes himself as "practically alone as an economist working in the music industry," tackled the issue in a paper he presented at the MCPS-PRS Alliance for Transmission conference in Vancouver, Canada late last year (he's executive director of research at MCPS-PRS, a London-based royalty collection society).
He calls the paper an attempt to "walk non-economists through the classic private-publicgood argument to illustrate where the price of recorded music is going." Among other things, he concludes that the music industry could prevent the price of music from falling to zero by making it "excludable" again, meaning that it should be possible to stop non-payers from accessing music -- not by applying DRM, but by selling content in bundles. He also points to supermarkets as one of the forces driving the price of music to zero.
I've been corresponding with Page since January about this, buthadn't written about it before because there was no way to link to thepaper. Now, MCPS-PRS has posted it online (PDF) so that everyone can have a look.
The basic idea, as summarized by the paper's introductory "key points" section, is as follows:
