In a server 70, usage counts of tone data of an electronic musical instrument 30, such as load counts of times that the tone data are loaded in the electronic musical instrument 30 are stored for each tone data and each user H utilizing the electronic musical instrument 30. When a recommendation information request is received from a portable terminal 50, the server 70 obtains a similar user similar to a request user included in the recommendation information request from the stored usage counts. Tone data to be recorded in the recommendation information are obtained from the usage count of each tone data of the request and the usage count of each tone data of the similar user, and the recommendation information is generated from the obtained tone data. Accordingly, the recommendation information generated by the user 70 can conform to the preference of the request user.
