"Let It Burn" is a song by American singer Jazmine Sullivan. It was written by Sullivan and Key Wane for her third studio album Reality Show (2015), while production was helmed by the latter. The song is built around a sample of "Ready or Not" (1989) by American R&B group After 7. Due to the inclusion of the sample, its writer Kenneth "Babyface" Edmonds is also credited as songwriter.
"Let It Burn" was written by Sullivan and producer Key Wane for her third studio album Reality Show (2015) and samples from "Ready or Not" (1989) by American R&B group After 7 as written by Kenneth "Babyace" Edmonds.[3] A throw-back to 1980s music,[4] the song is a dreamy, simmering late-night ballad,[4] that is built upon a synth-heavy instrumentation.[5] Lyrically, "Let It Burn" was inspired by a previous relationship during which Sullivan felt that she was not acting like an ideal girlfriend.[6] In 2019, she revealed that she almost failed to finish the song.[6]
Sullivan recorded her vocals on the song in one take.[4] Pre-produced by frequent collaborator Wane, she initially recognized the melody of "Let It Burn" as something she had heard before, but was not aware of the sample until months after she recorded it.[7] When asked about the sample, she commented: "I don’t mind samples if the feel is there. With “Let it Burn” the track felt so good that I couldn't imagine it without the sample, but I think it helped that I didn't know the original song."[7] Sullivan further described "Let It Burn" as a "classic song, a timeless R&B song."[8]
