“Sweet One” is a melodic, flex-heavy UK rap track by South London duo Osaze & Marcus, blending playful romance, lifestyle bragging, and cultural references with the duo’s signature smooth delivery. The song centres around a “sweet one from the south,” with Osaze and Marcus narrating a late-night link-up, luxury travel, and the difference between their elevated lifestyle and the ordinary men trying to compete. The track first caught fire on 3 December 2025, when Osaze (known individually as Ozzy Boy) posted a short snippet of the bridge and half of the chorus to his Snapchat. The clip instantly sparked hype, largely due to the now-viral bar: “Your ex boy is wasteman, ain’t seen a rack in his life.”
