That "Camp was a million years ago, sing me a different song"
Gambino is referencing his full-length album Camp here. This girl talking to him is getting tired of the same song he keeps singing, probably referring to what the content of the song entails. She is also tired of him singing songs like the ones that were in the album Camp and wants something new.
He also may be referring to the girl from the story on the last track of Camp (“That Power”) that he confessed his love to on the bus. He also uses the phrase “That camp” implying that this girl is referencing a camp they both attended.
Gambino is often referred to as continuously staying on the same topic of inequality and love songs in his music. This album is so different from Camp, and features totally new themes to those addressed in his past projects.
