I do remember discussing the Kill-a-watt, I was considering buying one but never did. It would be interesting to see the difference in power between playing music and idle as well. I think someone recently mentioned a similar device that jumped between 0 and 4 Watts on a Pi with nothing in between. A Kill-a-watt must have more resolution than that.
