Mathew Ingram spotlights the larger issue that is bedeviling music right now: how to get payment for what's rapidly becoming a commodity:

As Ethan points out, these kinds of concerns aren’t solely the province of the music business. Other content-related industries are struggling with the same issues: if content can flow in dozens of different ways, and in many cases is effectively free, how do content producers generate something meaningful that people will be willing to pay for?

Here's where I'd start: don't treat your customers as if their criminals. That's the bad place that the RIAA and the MPAA have gone, and it's the place we're all going with idiotic proposals like ACTA. The answer isn't to extend the DMCA across the planet. How's this: make it conveneient to pay, and see how that works out?
