A playlist editing apparatus includes a management unit 11 that manages a playlist, a playlist name input unit 12 for newly setting a playlist name, a determination unit 13 that determines whether conversion of a character code of a playlist name set for an existing playlist is required, based on a relationship with a character code of a set playlist name, a changing unit 14 that changes a character code flag of the existing playlist to a flag corresponding to a character code to be converted to, when it is determined that character code conversion is required, a character code conversion unit 15 that converts a character string targeted for conversion to a designated character code, in response to changing of the character code flag, and a playlist name setting unit 16 that sets the converted character string as the playlist name. This enables a playlist to be edited so that inconsistency in character codes throughout the playlist and the disk does not occur.
