The title track is a midtempo pop song produced by recent collaborator, Nao'ymt. The b-side track, "Nobody", was originally supposed to be included on the "White Light/Violet Sauce" single, but was removed before the single's release. "Nobody" is described as a direct sequel to "White Light" with which it shares an almost identical composition. The melody is altered in the verses but is identical in the prechorus and the chorus.
