Sound the alarms, Lorde [1] fans, because your favorite New Zealand singer-songwriter is back and apparently better than ever. After waiting more than three years for a follow-up to 2013's Pure Heroine [2], she's returned with not only a new single but also a music video. "Green Light" is insanely catchy and fun, and it has writer Jack Antonoff's synthy-pop fingerprints all over it. The release date for her new album, Melodrama, is still TBD, so in the meantime, feel free to listen to "Green Light" over and over and over and over . . .
