In 2011, KSI branched out into music, mainly as a Rapper. Starting out with fellow YouTuber Randolph, he released "Heskey Time", a rap song about Emile Heskey which was released on iTunes just before Christmas in 2011. The video features Heskey missing various chances on FIFA. Following the success of "Heskey Time", he began doing a segment on his channel called "Football Rap Battles", a video series, on which he and Randolph play the characters of famous figures from the world of football. Although it started off with raps featuring world footballers including Mario Balotelli and managers like Sir Alex Ferguson, one involves KSI as himself against Robin van Persie, hitting out at van Persie's acrimonious transfer from Arsenal to rivals Manchester United. He appeared in music videos with Droideka, directing and appearing in his music video for his song Get Hyper, whilst also collaborating with British Rapper Sway, releasing two tracks with the London born Rapper.
