Hmm. Tough choice, but based on the sci-fi genre, alien planet setting, themes of human corruption, and the detached, descriptive historical report format... the song "In the Sea of Corruption" comes immediately to mind.
It's an ambient soundtrack used in the movie "Nausicaa of the Valley of the Wind" for this toxic alien jungle setting which was created by human pollution:
Definitely more haunting/sad than comedic/satirical, but it's what came to mind for some reason :]
