The song came about when Aitch was in the studio with Mojam and they were showing him different beats. After choosing the instrumentation for "Buss Down," Aitch's manager got hold of ZieZie and the Londoner jumped on the tune straight away. The Manchester rapper recalled to Apple Music
"He came in the booth, started messing about, making melodies, and did a hook and a verse before I'd even written my first verse. It came about naturally and ended up being one of the sickest ones on the EP."
