Opponents of DRM will be thrilled over Engadget's post about FairUse4WM, an application that strips away the DRM restrictions from PlaysForSure music files. The application doesn't affect interoperability, though, because the files will still be in the WM format (though there are other ways to work around that).

Some record labels and the tech community may give this a lot of credence, but FairUse4WM is more a symbol of disruptive (from the view of the industry) technology than a practical problem. At A Copyfighter's Musing, Derek Slater downplayed the application's impact when he wrote "the online music DRM is so easy to get around that essentially no one gives a damn about actually circumventing it." With access to P2P so available, the need for a DRM-stripping application is almost nil.
