I have found the following about Zune Marketplace

Songs downloaded from the Marketplace are restricted by DRM similar to yet slightly different from PlaysForSure DRM, meaning that songs purchased from PlaysForSure partners could not be playable in Zune Software or on the Zune device, although the reverse is true.

Several entities have criticized the Zune for not playing PlaysForSureContent, including the Electronic Frontier Foundation. Internally, Zune DRM is referred to as "9.1", differentiating itself from PlaysForSure DRM, which is version "9". While removal of PlaysForSure DRM has been facilitated with several tools, none would remove Zune DRM until July 14, 2007 when one of the tools ("FairUse4WM" [Windows Media]) was updated to support removal of the Zune DRM wrapper. As of September 6, 2007, an update from Microsoft has broken FairUse4WM once again, with the effect that anyone with the updated license cannot remove the DRM. Updating the Zune software to the most recent version (3.1 as of November 2008) will not affect previously functioning DRM components.

Is it possible to remove DRM protection with FairUse4WM or any other software?
