The 18-year-old, who worked with Rodney Jerkins - producer of Jackson's 'You Rock My World' - on the song, said he watched a video of the pop icon to get him into the right mindset before recording.

"Before I got in the booth, Rodney showed me this hour-long video of Michael, never been seen before. It's Michael's personality, him in the booth dancing. It's some really special stuff. So me seeing that, going in there and being inspired and working with Rodney, who worked with Michael - it was incredible," he said.
