"Men in Black" is a 1997 rap/hip-hop song performed by Will Smith which coincided with the release of the film Men in Black. It can be heard during the closing credits of the film, and is featured on Men in Black: The Album as the first track. The song heavily samples Patrice Rushen's 1982 hit single, "Forget Me Nots" and also features vocals by Coko from the R&B group SWV. "Men in Black" serves as the signature theme song to the original film and the franchise as a whole.
In the song, Will Smith raps about how the MiB generally operates, how they protect Earth's citizens from extraterrestrial violence and of their highly clandestine nature (i.e. how they "walk in shadow, move in silence", etc). "Men in Black" was a major success taking the top spot on various Billboard charts. Will Smith won a Grammy for Best Rap Solo Performance for the single in 1998.
A short intrumental version of the song plays in the end credits of each episode of the Men in Black Series.
