DVD Jon, famous for breaking the encryption software that protected and localized DVDs, has reappeared, and this time he has attacked Apple's method of protecting iTunes bought from the Music Store.

The infamous Norwegian programmer Jon Johansen has found a way of buying DRM-free tracks. Because the iTunes Music Store doesn't add the digital rights management tag until a track has been bought and downloaded, Jon has devised a front-end called PyMusique that "conveniently neglects to wrap the file with any copy protection", writes engadget.

This isn't the first time Jon has challenged iTunes. Last January he cracked the digital rights management (DRM) protection features that protect legitimately-purchased iTunes music for GNU/Linux computers.
