The song's name is "Pound of Flesh". (Lyrics here.)
Psyche Corporation is part of the Gilded Age Records steampunk music label and its music has often been described as dark victorian fairytale science fiction.
To say a little more about "Pound of Flesh", it is themed on the risks and sacrifices that sometimes come with accessing knowledge or making knowledge accessible to others, and takes the general form of a talk the narrator is having with her disease.
Hope you enjoy!
