• This duet between a lonely robot girl and a human boy marked Porter Robinson's vocal debut. He used Vocaloid, a synth that recreates the human singing voice, for the female part. "I'd used Vocaloid as the vocals for several of the songs on Worlds, and then the idea of a duet between a lonely robot girl and the human boy who encounters her occurred to me," Robinson explained. "I didn't have much time before I had to turn in the entire album, so I just sang the male parts. I wanted something that felt distantly sad, a little cute, surreal, hopeful, and maybe somehow evocative of fiction."
• Another song about a robot's relationship with a human being is Royksopp's "The Girl and the Robot." In this instance Swedish vocalist Robyn sings about an ill-fated romance between a girl and a robot. Robyn also explored the idea of a futuristic synthetic mate on her solo single "Fembot."
