"One Of Wun" explores a range of themes that are characteristic of Gunna's lyrical style. One of the primary themes is street life, with Gunna reflecting on his experiences growing up in Atlanta and navigating the challenges of poverty and violence. Songs like "Sold Out Dates" and "Who Run This?" showcase Gunna's storytelling ability, as he vividly depicts life in the inner city.

The album's title, a play on the phrase "one of one," emphasizes Gunna's belief in his unique artistry and singular position in hip-hop. Released during a period of professional and personal rebuilding, the project finds the artist "unbowed, positive and defiant". neck on a yacht
