As a response to feedback from retailers and leisure operators, who are unable to benefit from custom-programmed music services because the CDs play on specialist proprietary devices, AEI Music has launched Dynamic Disc - a CD which, with the aid of a special filter, will play on the sites' existing CD players. The filter, which attaches directly to the CD player, decrypts the recorded music during playback, preventing pirating of the music. While still being able to play their own CDs, subscribers can also choose from seven different genres of music programmes, which are updated on a monthly basis.
