Music composition data transmission recording method and music composition reproduction device

Abstract

A song in a music player is replaced by another song in a server in accordance with the user's estimated preferences without requiring the user to become conscious of individual songs. A music player in a server detects a size of a free space in a memory and a playback history (a substantial playback count, which denotes the number of times a song was continuously played for a duration not shorter than a predetermined one, or a skip count, which denotes the number of times a song was played for a duration shorter than a predetermined one) of every song recording, and judges whether any song should be deleted from the memory to permit a song to be downloaded into the music player from the server. If any song should be deleted, a CPU selects a song having a small evaluation function as the song to be deleted.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This present application is a continuation application of and claims the benefit of priority under 35 U.S.C. §120 from U.S. application Ser. No. 10 / 550,064, filed on May 31, 2006, the entire contents of which are incorporated herein by reference. U.S. application Ser. No. 10 / 550,064 is a national stage application of International Application No. PCT / JP04 / 03770, filed on Mar. 19, 2004, which is based upon and claims the benefit of priority under 35 U.S.C. §119 from the prior Japanese Patent Application No. 2003-084245, filed on Mar. 26, 2003.TECHNICAL FIELD[0002]The present invention relates to a music data transfer / recording method for use in a music recording / playback system that downloads song data from a PC (personal computer) or other server for storing song data on a hard disk or other storage device to a music player for playing song data stored in a flash memory or other storage section.

AI Technical Summary

Benefits of technology

[0023]Further, the music player or server preferentially selects songs having a low substantial playback count or a high skip count as the song data to be deleted from the music player. Therefore, songs that do not presumably match the user's preferences will be deleted from the music player, whereas songs that presumably match the user's preferences will be retained in the music player. Furthermore, the server preferentially selects a song that has not been transferred to the music player and has been most recently registered in the server, as the song data to be transferred to the music player. Consequently, a song that presumably matches the user's preferences will be loaded into the music player.

Problems solved by technology

However, the aforementioned small-size, portable music player having a flash memory or other relatively small-sized memory cannot retain hundreds or thousands of songs.

However, the user finds it troublesome to select the songs to be deleted from the music player or may be at a loss what songs to delete.

The user also finds it troublesome to select the songs to be transferred from the PC to the music player.

The greater the number of songs stored on the PC, the more often the user is at a loss what songs to transfer.
