Unlike existing CD copy protection, which tries to make CD music files invisible or unreadable to computers and other copiers, Darknoise actually modifies the audio of the songs slightly. If those songs are then copied--even by holding a tape recorder in front of a stereo speaker--the formerly inaudible Darknoise addition becomes audible and makes the copy unlistenable, the company claims.

Satan, line 1.

Recording artists are gonna love this idea - spend $$$ on recording, mixing and mastering your music with 'golden ears' specialists just to have the distribution arm mangle the result.
