  2. Description of the Related Art Conventionally, as a technique for improving a user interface in a portable music player, there is known a technique capable of searching for a reproduction target by tracing a predetermined category hierarchy. For example, a genre, an artist, an album, a playlist, etc. can be adopted as a category forming a hierarchy. In this case, for example, genres, artists, albums, and music included in each album can form a hierarchical structure in this order. For example, the user can search for a reproduction target starting from any one of albums, artists, genres, and playlists displayed on the home screen and moving toward a lower category.

  For example, the user can display a list of albums recorded in the apparatus by selecting an album category on the home screen. Furthermore, any album can be selected and a list of music included in the album can be displayed. Similarly, by selecting an artist on the home screen, a search can be performed from the upper level to the lower level in the order of artist, album, and music. When a genre is selected on the home screen, a search can be performed while descending the hierarchy in the order of genre, artist, album, and music. When a playlist is selected, it is possible to search for albums and music that the user has registered in the playlist in advance.

  On the other hand, a music playback device that displays an image of an album jacket of the music or an image related to the genre of the music during playback of the music is also known (see, for example, Patent Document 1).
