Canadian pop superstar Shawn Mendes takes the idea of summertime sounds literally—just look at his inclusion of Drake's "Summer Games," A$AP Rocky's "Sundress," Weezer's "Island in the Sun," and Chance the Rapper's "Summer Friends" on his playlist. But even the selections that aren't literally about summer still have that sunny feel, whether it's MGMT's "Kids" or one of his own songs, like the new "If I Can't Have You."
