The new track sees Novelist rap over the same beat as JME's "P" from back in 2008.
Reload King will be Novelist's second album, after his 2018 Mercury Prize-nominated debut Novelist Guy.
Announcing the record earlier this month, the London rapper revealed it's "100% grime."
Earlier this month, Novelist added a verse to a remix of AJ Tracey's "Ladbroke Grove". On Four to the Floor TV in May, Novelist shared a huge new song that is yet to be released.
