Electro bass stabs and lush synthesizers mark the space age love song, with the rapper promising true love forever (or at least until the year 3005, hence the song's title). The tune is also rife with existential musings, with Gambino digging into the dark side on the second verse:

"I used to care what people thought/But now I care more/I mean, nobody out here's got it figured out/So therefore I've lost all hope of a happy ending/Depending on whether or not it's worth it."
