The technique was confirmed by BMG and SunnComm Technologies, the small company that produces the anticopying technology. Both companies said they had known about it before releasing the CD, and that they still believed the protection would deter most average listeners' copying.
"This is something we were aware of," BMG spokesman Nathaniel Brown said. "Copy management is intended as a speed bump, intended to thwart the casual listener from mass burning and uploading. We made a conscious decision to err on the side of playability and flexibility."
SunnComm's technology is the most flexible version of CD copy-protection to hit the market yet. It includes "pre-ripped" versions of the songs on the CD itself, each of which can be transferred to a computer, burned to CD several times, or transferred to many kinds of portable devices. These differ from unrestricted MP3 files in that only limited copies can be made, and not every portable music device can play them.
