This song was released a few months after Blondie's "Rapture
," which was the first big hit to feature a rap. Like "Wordy Rappinghood," it was rapped by a white female vocalist and beared little resemblance to the rap that was emerging from the New York City block parties.
Blondie and Tom Tom Club got some blowback from the CBGB's crowd for these songs, but were largely embraced by the hip-hop community, which saw how they were legitimizing the genre and pushing it forward. At the time, hip-hop was much more about the beats (typically played by a DJ) than the vocals, so any deficiencies in Debbie Harry and Tina Weymouth's flows were overlooked. An important distinction is that most rap music at the time was created by sampling and looping existing beats, but "Rapture" and "Wordy" had original music.
Neither act knew the other was working on a rap song - Blondie was recording theirs in New York while Tom Tom Club was busy in the Bahamas.
