“A dashing, long-haired, highly fashionable and occasionally gender-bending young Briton who dates pop stars and supermodels, makes free-love music videos, worships at the altars of Mick Jagger and Stevie Nicks and sells out arenas worldwide with his guitar-based, lightly psychedelic pop-rock? At times, Styles’ superstardom almost feels fictional, like some character a middle-aged writer would draw up for Russell Brand to play in a slapstick comedy.” Harry Styles Is the World’s Biggest Young Rock Star. Why Won’t Rock Radio Play Him? (Look, I’m just gonna say it and I don’t care who hears it. Watermelon Sugar High is clearly the song of the Summer.)
