"Motownphilly" is Boyz II Men's 1991 debut single for their debut album Cooleyhighharmony. The single was a success peaking at #3 on the Billboard Hot 100. Michael Bivins, who co-wrote the song, provides a guest rap during the bridge.
The video for the song was filmed in various locations in Philadelphia, the group's home city in December 1990. Two new jack swing groups, Another Bad Creation and Bell Biv DeVoe (of which Bivins was a member), are mentioned in the first verse: "Boyz II Men, ABC, BBD, the East Coast Family." Both groups appear briefly in the video, as does Sudden Impact, a short-lived, all-white R&B group organized by Bivins.
The song title etymology involves a combination of two of the group's main musical influences; 1960's Motown and 1970's Philly soul.
