The rapper admitted that he is keeping his fingers crossed that the track will make it to number one on Sunday.
"Any chart position, just to see people go out and download it and support it and buy legal, good UK music, is fantastic," he told BBC Newsbeat.
"Wherever I get, I'm happy. I'm totally grateful. The support has been immense already. It's like a dream come true. I couldn't ask for any more."
The 21-year-old claimed that he has been taken aback by the popularity of the song, which currently has a significant lead in the midweek chart.
"Obviously I knew that it was a big track," he said. "We had two stylists at the time and when we were playing the final track back they were just going, 'Charge now. Cast out. Lifestyle'.
"And I thought, 'Um. Maybe we might be on to something'. But never to this magnitude. It was just a track for the album. I'm happy everyone's really reacted to it so crazy like this.
