ABSTRACT:
A server apparatus operates a content sale site for selling a digital content and connects communicably via a communication network to a client apparatus which may purchase a digital content for use in an electronic music apparatus. In the server apparatus, a communicating section communicates with the client apparatus for receiving therefrom order information specifying a digital content to be purchased, and machine ID information designating machine IDs of electronic music apparatuses which are intended to use the specified digital content. A licensing section embeds the received machine ID information in the digital content specified by the client apparatus so as to license the specified digital content to the electronic music apparatuses designated by the client apparatus. A providing section provides the digital content embedded with the machine ID information to the client apparatus such that the provided digital content is made available exclusively by the designated electronic musical apparatuses according to the embedded machine ID information.
