The song "Rockabye" by Elijah Blake is about a late-night rendezvous with a girl, specifically a Brooklyn girl. The lyrics suggest that the protagonist has been awake all night, possibly eagerly waiting for a text message from the girl. When he finally receives the message, he decides that he can't wait any longer and must see her immediately. The lyrics mention that the girl is from Brooklyn, which represents a sense of urban sensibility and perhaps a vibrant and energetic personality. The line "Rockabye baby" is repeated throughout the song, which can be interpreted as the protagonist referring to the girl in an affectionate manner. The protagonist is determined to see the girl, even though he is speeding on the highway because he can't wait any longer. He mentions running low on patience but still not wanting to wait. This sense of urgency indicates his strong desire to be with her. The chorus repeatedly emphasizes the act of turning off the lights and turning the girl on, both literally and metaphorically. This can be seen as a representation of intimacy and passion between the two individuals. Overall, the song portrays a story of longing, desire, and a deep connection between the protagonist and the Brooklyn girl. The lyrics evoke a sense of urgency to be physically and emotionally close to her, and the repetition of certain phrases adds to the song's overall catchiness.
