So far, Ariana Grande's sophomore album My Everything has been previewed as a rousingly uptempo affair, what with "Problem," "Break Free" and the bonus track "Bang Bang" all conjuring their fair share of dance moves. The singer has unearthed her pensive side, though, for "Best Mistake," a new song which once again pairs Grande with her "Right There" partner.

"Best Mistake," which was released at midnight on Monday (Aug. 11), finds Grande and her beau trying to make up their minds about the future of their relationship, which deep affection buried underneath their problems. "If the water dries up, and the moon stops shining/Stars fall, and the world goes blind/Boy, you know I'll be saving my love for you, for you." Big Sean arrives midway through with a slippery verse, rhyming over little else than a bumping beat and an unfolding string section.

As of this morning, "Best Mistake" has reached the No. 1 position on the Bilboard + Twitter Trending 140 chart. Grande and Big Sean's previous collaboration, "Right There," peaked at No. 84 on the Hot 100 chart last August, and reached No. 37 on the Pop Songs chart in December.

Grande's My Everything album, due out Aug. 25, follows last year's debut full-length Yours Truly, which arrived atop the Billboard 200 albums chart last September. The first two singles from My Everything, "Problem" and "Break Free," have become Top 20 mainstays, with "Problem" peaking at No. 2 on the chart and "Break Free" climbing as high as No. 15.
