Claim:
1. A list display apparatus, comprising: circuitry configured to: generate a three-dimensional list picture, the three-dimensional list picture having a plurality of separate lower items, each associated with one of plural upper items and having respective predetermined lower item text in a hierarchical structure being unfolded and expanded in a mountain/valley-folded bellows configuration when shifting from an upper level to a lower level of the hierarchical structure such that each of the plurality of lower items is on a separate visually inclined portion of the mountain/valley-folded bellows configuration and the predetermined item text for each of the plurality of lower items is displayed on each respective separate visually inclined portion as inclined in a depth direction corresponding to a visual incline of the each respective separate visually inclined portion, or the plurality of lower items being folded and collapsed in the bellows configuration when shifting from the lower level to the upper level of the hierarchical structure, the circuitry generating the three-dimensional list picture by determining an inclination of one of the lower items with respect to a depth of the three-dimensional list picture upon a selection of an upper item in the upper level, wherein the plurality of lower items are displayed as being unfolded and expanded from a state of being invisible or folded and collapsed into a state of being invisible, while being attached to the upper item which is unaltered; and output the three-dimensional list picture to a predetermined display, thereby displaying the three-dimensional list picture as a hierarchical list on an angle in three dimensions once after an item of the three-dimensional list picture is selected for a playback, the three-dimensional list picture including at least a song title.
