Abstract: The invention relates to a method and apparatus for choosing a random group of musical selections which are housed in a prerecorded disk library and creating an individual customized tape cassette from the selections chosen. Through use of the present invention, a multiplicity of selections from a selection music library are chosen and electrically transmitted to a selection duplicating center where they are duplicated at high speed onto a blank recording tape cassette in the desired order selected. The duplication process is performed at high speed in order to enable the cassette to be made in only a few minutes from the selections chosen.
