Digital rights management has become the Net Neutrality of the online music industry, with traditional media companies on one side and device
makers, consumer groups and online music providers on the other. DRM is what keeps songs purchased on sites like Apple's iTunes from being played on hardware and software created by other companies.
Because of the popularity of its iPod media player, DRM has helped create a worldwide monopoly for Apple in online music, although Jobs said it would be better for all if Big Music consented to
selling regular old MP3s.
Warner's Bronfman fired back by saying that if Apple wanted interoperability it could license its technology to competitors, an idea backed by the Recording Industry Association of America, the organization representing traditional music companies.
