"Doin' It" is a song by American rapper Big Boi featuring Sleepy Brown, released as a single on February 1, 2019, through L.A. Reid's label Hitco.

Its release preceded Big Boi's Super Bowl LIII halftime show performance with Maroon 5 on February 3, and serves as his follow-up to 2017's Boomiverse.

[5] Rolling Stone echoed a similar sentiment, calling "Doin' It" a "radio-friendly pop-rap tune, with the Outkast emcee musing about eternal love over upbeat piano chords" and "Return of the Dope Boi" a "grittier cut full of staccato flexing and punctuated tag-teamed boasts, adorned with funk guitar stabs and orchestral synth lines".

[6] Spin thought "Doin' It" had "soul undertones", while "Return of the Dope Boi" featured "heavier production and a standout verse from Backbone".

[7] Writing for Forbes, Chris Malone Méndez wrote that "Doin' It" could "easily pass as a Lizzo song, which raises the question of how different it could've been with a chorus provided by the R&B songstress".
