The second single from Jay Sean's Neon album is a near-psychedelic ode to getting high with your lover that features YMCMB's family friend Rick Ross. The song was produced by Orange Factory Music, who comprise producers J Remy and Bobby Bass. The duo were responsible for the discovery and development of Sean.
The song is a classic R&B tune taking influence from soulful singers like D'Angelo and Maxwell. "There's this concept in mainstream music at the moment, Keep It Simple Stupid or KISS. It's this the way to satisfy the general public," Sean told Radio.com. "But for me, when you apply that, you take out some of the soul, some of the substance, and I don't want to do that."
He added, "You have to breathe the music. When I'm making that music, it's coming from the heart and there's nothing more open and honest to just say and sing what you feel."
The cut shows off Sean's falsetto. "Those songs, when you sing like that, tend to be sexy," he explained to Radio.com of using his higher voice.
The lyrics for "Mary, Did You Know?" were written by Christian singer and comedian Mark Lowry, after his pastor asked him to write a Christmas musical for their church. Southern gospel musician Buddy Greene later added music to his words.
