A Karaoke apparatus, a host apparatus and a management apparatus are interconnected to each other through a communication line to constitute a centralized system. The host apparatus receives an entry code requesting a Karaoke service of a desired song from the Karaoke apparatus through the communication line for supplying a music data of the desired song. The management apparatus receives an order code requesting an additional service other than the Karaoke service from the Karaoke apparatus through the communication line for attending to the order code and returning a response message. The Karaoke apparatus is equipped with an input tool having a primary use for inputting the entry code and a secondary use for inputting the order code. A transmitter distributes the inputted entry code to the host apparatus and distributes the inputted order code to the management apparatus. A receiver receives the music data from the host apparatus and receives the response message from the management apparatus. A player is operated for reproducing the desired song according to the received music data to thereby provide the Karaoke service, and a display is operated for displaying the received response message to thereby indicate how the additional service is managed.
