In the 1950's-inspired production, Dwight & Nicole are cast as a pair of scientists who build a robot boy. They strive to teach Robot Boy everything that they possibly can, but have difficulty teaching him to smile - hence the title of the song.

"Smile" can be found on Dwight & Nicole's most recent record Shine On, which Nicole spoke with The Voice Examiner about in April. "What I love about the album is that it touches on multiple layers of feeling and expression," she explained in the interview.
"What I feel like has happened in popular music is that things get boiled down and fine-tuned in order to sell them easily to a market. Which makes sense as a business. But what I miss about old records that I love is that they dive deeper than that and tell a 360 degree story. All of these inflections of personality come through."
Nicole was previously a member of Team Adam during Season 3 of The Voice.
Shine On is available now on iTunes; for more on Dwight & Nicole, be sure to visit their website (dwightandnicole.com) and follow them on Twitter (@dwightandnicole). You can also follow Nicole herself on Twitter (@nicolenelsong).
