“Lights Up”, Harry Styles (5/20)

This song was releases as the first single from Harry’s second album, “Fine Line”. The hit had an impressive marketing campaign – days before its release, numerous billboards appeared worldwide with the phrase “Do You Know Who You Are?”, a line taken from the song’s lyrics. Also, a website named “Do You Know Who You Are?” was set up. The website offered compliments to those who typed in their names, not a bad way to earn the public’s love!
