A digital musical recording is a material object--
“(i) in which are fixed, in a digital recording format, only sounds, and material, statements, or instructions incidental to those fixed sounds, if any, and
(ii) from which the sounds and material can be perceived, reproduced, or otherwise communicated, either directly or with the aid of a machine or device.
(B) A "digital musical recording" does not include a material object--
(i) in which the fixed sounds consist entirely of spoken word recordings,
(ii) in which one or more computer programs are fixed, except that a digital musical recording may contain statements or instructions constituting the fixed sounds and incidental material, and statements or instructions to be used directly or indirectly in order to bring about the perception, reproduction, or communication of the fixed sounds and incidental material.
(C) For purposes of this paragraph--
(i) a "spoken word recording" is a sound recording in which are fixed only a series of spoken words, except that the spoken words may be accompanied by incidental musical or other sounds, and
(ii) the term "incidental" means related to and relatively minor by comparison.”
