And as reports are already flowing in about the song, it looks like this song will set him apart as one of the world's most exciting new music star.
Following in fellow former One Direction mate Zayn Malik's footsteps, Harry Styles has finally made his transition from one-time boy bander to solo artist with the release of his own first single.
"I think she leads by example, she's the biggest, and she's wonderful she's the best so she should be the biggest". I don't think so. I feel like with all of the stuff how people date now with all online stuff I feel like you can do that (Google) with anyone really. It's the band, it's one thing. "It's the song I'm most proud of writing, I think".
Harry Styles went to Taylor Swift levels of secrecy to keep his highly anticipated debut solo single under wraps.
He dropped the first single, "Sign of the Times", earlier today (April 7) and opened up about writing and recording the new material in Jamaica.
He added: "As a credible piece of indie-pop balladry that moves Styles into a new arena, I'd say he just about pulls it off".
"I took, like, a month and then started to realize I like doing stuff, so I got a little bored", he told Carson Daly on 97.1 AMP Radio.
While talking about dating, the "History" hitmaker said that he could not date for a long time because he was away doing a movie and focusing on his recent album, which released this April. 7.
He's also a big fan of his pal Ed Sheeran, who listened to some of his album before its release. And that's not because I don't have anything else to listen to or do, it's just that good! "He [Ed] is really good - he's one of the most talented dudes I know".
Styles will perform on Saturday Night Live next Saturday, April 15 with Jimmy Fallon hosting.
