They described the new album as organic, live, more drums and guitar, less electronic, different but not too different from MM and liam described it as "proper music" so yeah
i still think they're gonna have some r&b incorporated into a song or two tho
Zayn's songs with naughty boy are the ones I think will have some r&b incorporated with in them, they usually do have one or two experimental tracks that are different from the rest of the album
