Abstract
A tree display is made in a tree display area of a play list display area as of the contents files were classified in a directory structure, but in reality the contents files are not classified in a directory structure. In the tree display area, the heading “All music pieces” is not located at the lowest hierarchical level of the tree structure but partway up the structure, and in the event that “All music pieces” is selected, the contents are searched with an item corresponding to the parent thereof as the search key, and data relating to the corresponding contents is displayed in a list display area, so in a case described herein, contents matching the genre of “Blues” and artist name of “4 hero” are displayed on the list display area. Thus, desired contents files can be easily searched for.
