Opinions on P2P

I do not believe in surveys, or in what people say -- too often it is contradicted by what they actually do. So I am not moved by this Canadian survey which argues that P2P music sharing does not impact CD sales. Instead, I would look at the fact that while downloading mp3s off the internet has become normal, mainstream activity, CD sales have barely budged. For reasons which honestly are quite beyond me, a downloaded mp3 seems to be a very pure substitute for the CD. This must be because most mp3 downloads are substituting for CDs that were never bought.
