The 26-year-old rapper has dropped the track, named 'Hit 'Em With The Draco', ahead of his proposed boxing match with the 'Loyal' hitmaker which was scheduled after the pair engaged in a public feud on Twitter earlier this month.
In the track, Soulja Boy - who is reportedly receiving training for the fight from former world boxing champion floyd mayweather - promises to ''knock Chris Brown out when I see him''.
The lyrics to the song read: ''Ayy 50 Cent what you talking about? / You made all that money off Vitamin Water and then filed for bankruptcy / You know I'ma knock Chris Brown out when I see him.''
Chris and Soulja Boy are expected to come to blows sometime in March, and are reportedly planning on screening the battle on Pay-Per-View television.
The feud kicked off in early January after Chris vowed to fight the 'Kiss Me Thru The Phone' rapper - real name DeAndre Cortez Way - for liking a picture of his ex-lover Karrueche Tran.
Soulja Boy then raged on Twitter: ''Chris brown just called me and said he wanna fight me because I liked @karrueche picture on Instagram this n**** a b***h
''Aye @chrisbrown pull up n***a I'll knock yo B***h A** out stop snorting so much coke n****. FRUITS
''That n**** @chrisbrown better not tweet s**t with his p***y a**. He called my phone trippin so now I'm trippin F**k n****. Fruits! (sic)''
Soulja Boy also roamed the streets looking for Chris and attempted to entice him into a brawl before they announced their planned boxing match.
