It was written by Rico Love, Kevin Cossom and produced by The Runners and The Monarch for his fourth studio album D.N.A.

"Thinkin' About You" was written by Kevin Cossom and Rico Love and produced by Andrew Harr and Jermaine Jackson from The Runners as well as Andre Davidson, Sean Davidson, and Karlyn Ramsey from The Monarch.

[3] The song was originally set to include a guest feature from rapper Diddy.

[4] Another leak of "Thinkin' About You" was a duet with fellow R&B singer Kelly Rowland.

[5][6] A reviewer for music website Djbooth.net said, "With the follow-up single, the singer reaches out to fans of his more traditional R&B balladry in addition to the club crowd" also, he adds "As if Mario’s Trey Songz-esque vocals and Rico Love‘s songwriting weren’t enough to sweep this female off her feet, The Runners heighten the ambiance yet further with a steamy, synth-packed instrumental".
