In 2012, Chainz signed with Def Jam Recordings, and released his debut album "Based on a T.R.U. Story" to commercial success, spawning "No Lie" (featuring Drake), "Birthday Song" (featuring Kanye West), and "I'm Different", all of which charted in the top 50 of the Billboard Hot 100, as the singles were certified Gold along with the album.
His second album "B.O.A.T.S. II: Me Time" was released in 2013; supported by the single "Feds Watching" (featuring Pharrell Williams).

Several EP's and Mixtapes would lead to his fourth album "Pretty Girls Like Trap Music", which featured Travis Scott, Nicki Minaj, Swae Lee, Migos, Jhene Aiko, and Pharrell Williams. The album was supported by "Good Drank", "It's a Vibe," and "4 AM"and received critical acclaim, as his best album.
