Childish Gambino and SD hop on J. Cole’s “Who Dat” instrumental to add a little more flavor to the original. The track is off of Paul Rosenberg’s latest mixtape, which he recently put together.

There’s a sad story revolving around SD — he was close to Rosenberg and was killed in a car accident at age 18 — recording this verse before he passed away.

Gambino, as always, delivers with his witty punch lines.
