PCM is an encoding of sound, not a composition. A composition, to varying degrees depending on the composer, leaves various degrees of freedom for the performance. So the PCM encoding of a performance is entirely different to the composition ... conceptually. However, a good musician may be able to listen to the PCM encoding (aka "digital audio") and from that frame their own understanding of the composition, thus leading to a new performance. So .. it's complicated.
