Home Theater Magazine has an interesting Q&A with the RIAA titled "Sympathy for the Devil" that's worth a read. The questions were submitted by email and the answers published without futher comment. Snipet:
9. EMI seems to be doing well with DRM-free downloads. Other record labels, like Warner, are more skeptical of the idea. Is there a strong interest among your membership in selling DRM-free music?
We will see. There's a lot of experimentation going on in the marketplace right now. EMI is one such example. Obviously, everyone is paying attention closely and we will have to see how it plays out.
It's probably worth noting that most of the experimentation involving DRM-free music is with pure downloads. DRM remains an indispensable tool for other business models, like subscription services, or pre-loading content, because without DRM, those models could not be offered to consumers.
