I was enticed to this track because it has such a haunting melody and general vibe. It has always reminded me of "I'm only Human" by the Human League. It has some very similar chord progressions. I use a nylon stringed classical and electric guitars, as well as bass to pick out the tune.
"Come Back to Me" is by Janet Jackson, taken from her fourth studio album, Janet Jackson's Rhythm Nation 1814 (1989). It was written by Jackson, while James Harris III, and Terry Lewis co-wrote and produced the song.
