A method, the method being executed via at least one processor having circuitry, and comprising:

• receiving, from a server, a plurality of content data corresponding to a plurality of content identifiers in a list,
• transmitting the plurality of content data to a reproduction apparatus,
• deleting a content identifier from the list when the corresponding content data is transferred to the reproduction apparatus,
• receiving a first request to resume the transfer from the reproduction apparatus after the transfer is interrupted,
• acquiring remaining content identifiers in the list of the reproduction apparatus in response to the first request,
• producing a second request for requesting transfer of content data corresponding to the acquired remaining content identifiers that remain in the list after the deletion of the content identifier from the list, and
• receiving the content data corresponding to the acquired remaining content identifiers from the server.
