Copy-blocked CD tops U.S. charts

The test with Velvet Revolver, a group made of alumni from Stone Temple Pilots, Guns N' Roses and others, was the largest yet for BMG. The test uses MediaMax copy protection from BMG partner SunnComm International. The label says it does plan a growing number of protected releases over the course of this year, but is still choosing which CDs will include the technology on a case-by-case basis.

As in earlier tests by BMG and SunnComm, the copy protection on the Velvet Revolver disc can be simply disabled by pushing the "Shift" key on a computer while the CD is loading, which blocks the SunnComm software from being installed. The companies say they have long been aware of the work-around but that they were not trying to create an unhackable protection.

However, the inability to move songs to Apple's popular digital music player, as well as to other devices that don't support Microsoft's Windows Media digital rights management services, is a serious shortcoming. Jacobs says SunnComm recognizes that--and that the company's next version will go beyond the Microsoft files and be able to create multiple kinds of digital files that will be compatible with the iPod.
