Producer: Super Mario
Album: 1017 Thug (2013)

It's the spelling, of course. The first verse of “2 Cups Stuffed” opens with that famous sequence: “L-E-A-N-I-N-G/Lean, lean, lean, lean, lean, lean, lean!/Five-hundred horses/Inside my machine!” 1017 Thug was so arresting, such a star-in-waiting announcement because Thug showed he could be effusive in so many ways. “Picacho” is manic; on “Nigeria” he sounds as if he’s on the verge of tears, desperate to get his point across. But it’s “2 Cups Stuffed” where Thug’s focus is laser-precise, where hundreds of horses are no match for some Styrofoam and a little bit of improv. —Paul Thompson
