The song was originally intended as a duet with longtime rival _Prince. Quincy Jones, in an interview included in the Special Edition of "Bad", said that Prince told Jackson and him that he hadn't wanted to participate because "it would be a hit without (him)".

In his 1988 autobiography Moonwalk, Jackson wrote: "Bad" is a song about the street. It's about this kid from a bad neighbourhood who gets to go away to a private school. He comes back to the old neighbourhood when he's on a break from school and the kids from the neighbourhood start giving him trouble. He sings, "I'm bad, you're bad, who's bad, who's the best?" He's saying when you're strong and good, then you're bad."

In 2006, the single, as well as the video, was re-released as part of the Visionary - The Video Singles package.
