When Harry Styles goes solo, he really goes solo. Early Monday morning, the One Direction singer released the music video for "Sign of the Times," the debut single from his solo album (out Friday). "I think Sign of the Times,' just in terms of honesty, is a good representation of the album, but I don't know if it all sounds exactly like it," he said. "I think it's impossible to not be influenced by stuff that you grow up listening to?stuff that my parents played and stuff that I still listen to now."
