—but I'll take a crack at it based on what I know about the area, briefly.
It's really a question, when you look at those legitimate sites, about the licensing fees that have been negotiated and what they ultimately pass on to artists, whom you hear from. It's also a question, when you talk about a site like YouTube, of the enforcement that's on that site to try to prevent illegal content from being on it.
YouTube is usually held up as having fairly robust systems to police that sort of thing, so maybe we would talk about some other site. What you're really seeing, when you look at those legal sites, I think is a change in the balance of what those companies take and what they pass on to the artists.
