Man, I hate it when that happens.
I listened carefully to the song, and I can verify that it indeed lacks any singing robots, Martian or otherwise.
A fine song - nicely mixed, like stepping into a jazz club with a more-than-competent band, and someone who was paying attention behind the mixing console.

But having gotten Chekov's gun in my head, I couldn't help but wonder: what
would it have sounded like with a singing robot?
