By channeling Oasis.
Liam, Niall, Louis and Harry are hard at work on their fifth album, the first since Zayn Malik left the band in March, and much like their previous efforts, they've been embracing their love for rock music.
"The album's coming together really well actually," Liam told Capital FM. "The boys we've been writing with have come up with some great, great songs that are kind of like a bit Oasis-y almost, which is ace. I love that."
In between Liam's new job as a pool cleaner, he and the rest of the guys have been in the studio with frequent collaborator Jamie Scott, who co-wrote "Night Changes" and "Story of My Life," and are hoping to create a "long-lasting" album, much like their BFF Ed Sheeran.
"The songs have come out a bit more chill because I think we want this to be quite a long-lasting album that you can listen to anytime," he said. "You like how Ed's album, anytime you can throw on an Ed song and it can always make sense. We're trying to do that."
Fingers crossed that Ed and the foursome team up once again for their album, which is due out later this year, because "18" and "Little Things" are nothing short of perfection.
