The economic effects of piracy on the music industry

The Long Tail: "Just enough piracy"

A very interesting post on digital rights management (DRM):

...The second reason the quest for zero-piracy is a mistake is an economic one: piracy can actually let you raise your prices.

The discussion that follows gets much more interesting in the comments down. Spend some time at this link and I promise you'll understand both sides of the piracy/DRM problem.
