An electronic music apparatus has a sound generator for generating a music sound signal according to music data and a display device for displaying information associated with music data. In the electronic music apparatus, a storage medium stores a plurality of music data files, each being written with music data for use in generating the music sound signal. An information retention section retains file information for use in displaying a name or an icon of the respective music data. A reading command section issues a command of reading out a target music data file from the storage medium. A display control section controls the display device when the target music data file is successfully read out, for displaying the name and the icon of the music data written in the read target music data file based on the file information, and controls the display device when the target music data file is failed to be read, for displaying 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 out.
