At a high-level your logic is correct, Sam.
However, if one "takes out the skin of hair", power consumption does (at the micro/milli-watt level) vary based on the processor / chip and the audio format. That is due to the number of instructions required to decode one compression format or the other.
Another factor is the HDDs inherent power consumption.
Of course, at that level one has to consider that higher the volume one listens music to, greater is the power consumption.
