Abstract An information storage medium such as a CD-ROM has a storage area which stores digital audio information including music digital audio information and a plurality of music piece information having mark information for retrieving the accompaniment information, and a digital contents information table including music title information which represents titles of the music piece information with image information or voice sound information. The storage area is divided into a plurality of sections. Some of the sections which precede the other sections in time store the digital contents information table. The other sections store the digital audio information. An apparatus for reproducing information from the information storage medium selectively reads the music piece information based on the mark information.
