  In this way, the comment information has a display time of about 10 seconds as described above, and the comment display area selection means 408 displays the comment when the comment information can be displayed in the comment display reference area 412. When the reference area 412 is selected and the comment information cannot be displayed in the comment display reference area, the comment display divided area having the smallest display range among the comment display divided areas 413a, 413b, 413c, and 413d. The process which selects sequentially is performed.

  For this reason, the display position of the comment displayed at the time of reproduction of music data is random according to the number of comments transmitted by the user. In this embodiment, since the comment display division areas 413a, 413b, 413c, and 41d are arranged in a semicircular shape with the comment display reference area 412 as the center, the displayed comments are also displayed in the comment display reference area 412. Will be displayed so as to spread in a semicircular shape.

  Therefore, each time the user repeats the reproduction of the music data, the user cannot predict where the comment input by the user or the input by another user will be displayed, and a semicircular shape centering on the comment display reference area 412. It is possible to visually enjoy comments displayed randomly so as to spread.

  In addition, since the random display of comments is visually transmitted to the user, the input of comments is promoted, and a comment display rich in variations can be provided according to the number of input comments.
