Lil Baby comes out of Atlanta's melodic trap scene, known for sharp, fast-moving rhymes with a strong sense of melody over booming trap drums. These beats are made for that kind of confident, melodic delivery.
Every one of them is hip hop and nearly all are trap. More than half feel bouncy or confident, some are built around guitar, and some also carry Lil Durk or Roddy Ricch tags.
Start with "Raw", the most-viewed beat in this set on YouTube.
