Matty B

Ten-year-old pop prodigy MattyB has returned with a new single for his million of YouTube fans, this time from the upcoming film "Free Birds." Check out "Back In Time," debuting exclusively on Billboard.com, below:

The Atlanta native's cousin, Marshall Manning, wrote "Back In Time" in a single day before producer Justin Reinstein hopped aboard to helm the track. The track showcases the accessible pop-rap that MattyB has been creating since the age of 7, and will appear in "Free Birds," an animated film due out in theaters on Nov. 1.

"This song and music video was the most fun I have ever had on a project and it turned out awesome," says MattyB (real name: Matthew Morris) about "Back In Time." "This song is definitely going to be my favorite to perform, and I really hope my fans love it as much as I do."

The music video for "Back In Time" will be unveiled on Monday (Sept. 30), which is also when the track hits digital retailers. The song premiere is just in time for our annual 21 Under 21 list! Check out where MattyB landed on this year's ranking.
