The album's first single and opening track, "He Wasn't Man Enough", was written and produced by Rodney Jerkins. The R&B song, with synth-funk bassline and Jerkins' taut beats and harp, has Toni warning a female friend not to marry a man the singer knows all too well and that came back begging for forgiveness. On the title track, "The Heat", co-written by Keri Lewis, was described as "an infectious mid-tempo groove." Lyrically, the song talks about wanting to "get it on" and enjoying coed skinny-dipping. Third track, "Spanish Guitar" ,was written by Diane Warren (who wrote "Un-Break My Heart") and was considered a "latin ballad", inspired by "Un-Break My Heart". Lyrically, the song has the singer inviting an alluring stranger to play her "through the night" like a "Spanish Guitar." The fourth track "Just Be a Man About It" is a telephone breakup song, with Toni once again questioning the status of a partner's manhood and Dr. Dre playing the wayward lover breaking the news to her, while fifth track, "Gimme Some", features Lisa "Left Eye" Lopes and was named "an R&B/summer 'jerky funker' track", with Braxton demanding intercourse and oral sex from a man.
