FairUse4WM strips the Windows Media DRM . . . for now. We’ve been here before: software strips DRM, user rejoice, DRM manufacturer changes algorithm and renders stripped tracks useless, DRM stripper programmer guys re-work stripping software around new algorithm, etc.
In any event, while it works, FairUse4WM, as the name implies, strips the DRM from Windows Media files, meaning that if you are signed up for Napster or some other similar service, you may be able to download a bunch of songs and keep them rather than just subscribe to them (not that I am condoning such a thing).
Engadget has tested it out and it seemed to work for them.
