<p>PROBLEM TO BE SOLVED: To determine a delivery music piece suiting each user's taste. SOLUTION: Request data of an object user is read out to statistically operate the user level (S1). A first higher order group to which the object user belongs is specified (S3), and statistical operation using personal information of the user belonging to the specified group is performed (S5). This processing is executed as far as the higher order group exists (S5, S7). The total points are computed (S11), and according to the computed total points, the delivery object music pieces are rearranged and delivered (S13). Thus, the points of the group to which the user belongs are computed to perform integrated determination, whereby when there is a small amount of the request data on the concerned user, a delivery music piece suiting the user's taste can be delivered.</p> |
