Pop-friendly stalker music. Chugging electric guitars, electric bass, B3 organ, acoustic drums and creepy synth pads slowly build to give you the feeling that a knife-wielding maniac is watching your every move. @:19, a "Psycho"-like screeching, heavy synths and a general sense of chaos signals that he catches you and starts stabbing you with abandon, which hurts far less than being stabbed with, say, a knife. The second half is similar, except from :30 to :49 where the music is less threatening and more positive, which provides a greater contrast when the stabbing begins @:49. 105 bpm (Amaj)
