There was not a bigger, more contagious crossover radio smash in the autumn of 1991 than Naughty by Nature's "O.P.P.," a song that somehow managed the trick of being both audaciously catchy and subversively coy at the same time. The lead single off their eponymous album, it was one of the first rap songs to become a pop hit when it reached No. 6 on the US Billboard Hot 100 and No. 35 on the UK Singles Chart. It even named one of the 20 greatest singles of the 1990s by SPIN magazine. The third single off Naughty By Nature, "Uptown Anthem," is the b-side on this 7". Originally made for the soundtrack for the movie Juice, the song peaked at No. 27 on the Hot Rap Singles chart and No. 58 on the Hot R&B Singles chart.
