Known for her wistful love songs and electronic ballads, Ellie Goulding has one of the most versatile voices in the biz—in other words, she's a remixer's dream. She's amassed quite the collection of reworks, too, featuring the likes of American dubstep hero Bassnectar, French turntablist crew Birdy Nam Nam, club veteran Alex Metric and trance superstar Tiësto.
