"Monster" is a song by American recording artist Lady Gaga, from her third EP, The Fame Monster. Inspired by her "Fear of Attachment Monster", the record was written by Gaga, RedOne and Space Cowboy, with RedOne producing the track. Gaga had explained that "Monster" describes her fear of sex and relationships, and described the lyrics as being in love with the bad boy all the time, but instead of running away, one keeps going back to the same person. She added that the fear in "Monster" erupted from her need to have a stable relationship. Incorporating the usage of heavy bass lines, descending keyboard lines and "massive" choruses, "Monster" contains zombie like metaphors, and a reference to Gaga's debut single "Just Dance".
