The musical choice was very fitting: as the singer was able to carry a tune yet wasn't a "beautiful" voice, the closing was suitably grim and awkward, and the piano was such a jaunty tune that works against the subject matter. I thought the facts were funny and made for some clever lyrics.
I was blown away by the one about the cost of the death penalty; It seems like the cost is highly inflated because of court costs rather than some sort of magical money drainage.
