Abstract
A method for performing playbacks of pieces of music recorded on recording media, in which a subsequent piece of music to be played back is randomly selected among pieces of music which do not correspond to any playback-inhibition identification numbers nor any playback-completion identification numbers both of which have been already stored in a memory. The memory includes two regions 'A' and 'B', in which 'A' are stored the playback-completion identification numbers, and in which 'b' are stored the playback-inhibition identification numbers. Immediately before the randomly-selected playback is produced, the identification numbers stored in the region 'B' are transferred to the region 'A' so that the subsequent piece of music is randomly selected among the pieces of music which do not correspond to the identification numbers of which are not stored in the region 'A', whereby the randomly-selected playback can be repeated, without necessity of repeated procedure for designating any music pieces which are prohibited from being played back.
