UPDATE: Based on one-day projections, Styles' new single is headed for a first-week number of 100-150k in song activity. This is the first track from the One Direction frontman since his debut self-titled album, released in May 2017. "Lights Up" bowed at #2 on Spotify's daily U.S. streaming chart and and topped the iTunes singles chart. 

After a week of teasing fans with a new website and promotional banners, Columbia's Harry Styles delivered his new single "Lights Up" on Friday. He sings "Do you know who you are?" during the pre-chorus, which is also the phrase he built his campaign around. Watch the video below.
