Engineered and mixed by Kevin Beamish, "Love Machine" was produced by Freddie Perren, a former member of The Corporation brain trust in charge of the early Jackson 5 hits. It was written by Billy Griffin and his Miracles group-mate, original Miracle Pete Moore, with whom he wrote the rest of the "City of Angels" tracks as well. The song's lyrics, delivered over a disco beat, compare a lover to an electronic device such as a computer or a robot. The seven-minute song was split into two parts for its release as a single, with "Part 1" receiving most notoriety.
