Writing a pop smash depends on the ability to read the temperature outside. DJDS—aka the LA producers Jerome LOL and Samo Sound Boy—are expert forecasters who are breaking away from their beat-making past to explore the modern pop spectrum. With their earlier summer anthem “Trees on Fire,” they proved it was a strong decision. “Why Don’t You Come On” is an equally immediate earworm, a positive plea for peace and togetherness, exalted by the twin vocals of the Texan teen sensation Khalid and the L.A. wunderkind Empress Of.

Khalid plays headliner here: His voice is a gritty baritone that sounds accidentally sexy, like the unintended gravel a voice gains from a chest cold. It lays down the track’s backbone, making room for Empress Of’s saintly high notes. DJDS possess the confidence and playfulness to juxtapose these two starkly opposing styles with ease: the minimal drum and synth rhythms that skitter around them complement both Khalid’s yearning voice and Empress Of’s angelic flow. “Why Don't You Come On” is an ideal cap to a scorching night, its beat as refreshing as a blast of cool air.
