Harry Styles' solo material will be rock-influenced.

With One Direction officially on hiatus, the boys have gone their separate ways in terms of producing their solo material - Liam has been working with Juicy J, FYI. But the latest news is that Harry Styles is currently working on his solo album, focusing on it having a rock & roll feel to it (which I could totally envision him doing).

An anonymous source exclusively told Hollywood Life that Harry has been: "Very busy putting the finishing touches to his solo career, recording new material in London and just trying out new things. It's a new chapter in his life, and he wants to make sure that everything is right as he makes his next step. Harry is looking at Robbie Williams, and how he achieved success outside of Take That. He's working with the best songwriters and producers, aiming for a more rockier sound that'll be a lot different than what fans expect.

With that being said, I realllllly want his new material... like now.

But until then, reminisce about the boys in their karaoke video below...
