From Nate Anderson’s “Hacking Digital Rights Management” (Ars Technica: 18 July 2006):
A third approach [to subverting Apple’s DRM] came from PyMusique, software originally written so that Linux users could access the iTunes Music Store. The software took advantage of the fact that iTMS transmits DRM-free songs to its customers and relies on iTunes to add that gooey layer of DRM goodness at the client end. PyMusique emulates iTunes and serves as a front end to the store, allowing users to browse and purchase music. When songs are downloaded, however, the program “neglects” to apply the FairPlay DRM.
