I want to know the answer to the following question:
What did Sinnreich call the link between lower music sales and peer-to-peer sharing site?
All the background I'm provided with is that "He argues that the industry at the time was undergoing artificial expansion, what he describes as a "'perfect bubble'—a confluence of economic, political, and technological forces that drove the aggregate value of music sales to unprecedented heights at the end of the twentieth century".". Is that enough to answer the question?
Answer: no
