This was NOT an MP3 player by Amstrad, yet it was quite a nice product to have. It was a device that you could connect to your monitor and turn it into a nice television set for your bedroom. Quality and reception was not stellar, but still it was very good value for money. Don't imagine any fancy stuff like watching TV in a window or anything - the tuner just used the monitor for its output.
It was an interesting reversal of logic: the CPCs shipped with monitors in order to free the home TV from computer use - and then was turned into a TV set itself.
