"Dangerous" took over a year in production, and was produced by Jackson with additional production from his friend Bill Bottrell and Teddy Riley.  Jackson wrote twelve of the fourteen songs on the album.  Lyrical themes expressed on the album included racism, poverty, romance, the welfare of children and the world and self-improvement, topics Jackson had covered before.  Nine singles were released from "Dangerous" between November 1991 and December 1993, with seven singles issued in the United States, and two others released only outside the US.  The two singles released outside the United States were successful, charting within the top ten and top forty respectively.  "Dangerous" peaked at number one in nine countries, while charting at the top ten in four other territories.  The only songs not released as singles were "Why You Wanna Trip on Me", "She Drives Me Wild", "Can't Let Her Get Away", "Keep the Faith" and "Dangerous"; a video and a single release for the latter was said to have been planned, but was postponed indefinitely due to the musician's tour and allegations of child sexual abuse in 1993.
