With all of the Big Four record labels now jettisoning digital rights management, music fans have every reason to rejoice. But consumer advocates are singing a note of caution, as the music industry experiments with digital-watermarking technology as a DRM substitute.

"It gives them the ability to put pressure on policy makers and ISPs to do filtering," said Fred Von Lohmann, an Electronic Frontier Foundation attorney. (Wired)
