I'd imagine this would be pretty impossible to do in MP3 form, or Wave form for that matter. A computer program, I doubt could think of music in the same way we do, and actually pick out a track persay.
You could find a MIDI of the song though, which would contain the synthersizor data, that someone may have made. Worth checking out.
But then, you'd only have the notes, and would need a good sound to play back the data.
