Yes, I do need a scientific study. When Napster came out my friends and I finally had access to hard-to-find singles and b-sides that were not available anywhere else. We also still bought tons of records. I'm looking at Napster now - it feels a lot like Pandora and Spotify. I can't take an anecdotal story from a company ('the story of Napster') and treat that as hard evidence in a fact-based argument, sorry.
