An electronic music apparatus has a sound generator for generating a music sound signal according to music data. A storage medium stores music data files, each written with music data for generating the sound signal. An information retention section retains file information for displaying a name or an icon of the respective music data. A reading command section issues a command of reading a target music data file from the storage medium. A display control section controls a display device to display, when the target music data file is successfully read out, the name and the icon of the music data written in the read target music data file, and when the target music data file is not read, to display the name and the icon of the music data in a state different from the name and the icon displayed when the target music data file is successfully read.
