Young Thug, Pharrell and Ariana Grande are on Calvin Harris' second star-studded single of the year with "Heatstroke." Cop it on iTunes or stream it via Apple Music below.

Earlier this year, Calvin dropped "Slide," a blockbuster single featuring Migos and Frank Ocean. That was enough of a summer banger, but it looks like he's piling on with "Heatstroke," which also includes background vocals from songwriting superstar Starrah.
