A method for the creation and playback of recording industry music and audio, such that each time a composition is played back, a unique audio version is generated in the manner previously defined by the recording artist. During composition creation, the artist's definition of how the composition will vary from playback to playback is embedded into the composition data set. During playback, the composition data set is processed on a playback device by a specific playback program the artist specified, so that each time the composition is played back a unique version is generated. Variability occurs during playback per the artist's composition data set, which specifies the spawning of group(s) from a snippet, the selection of a snippet from each group, editing of snippets, flexible and variable placement of snippets, and the mixing of multiple snippets to generate each time sample in a channel.
