The 23-year-old former One Director star released his first solo single "Sign Of The Times" earlier this year.
"I'd done a couple of writing sessions and they hadn't gone so well and I got in this hole of 'I don't wanna make music any more' I just had this massive block, then went into a room with three guys I hadn't met before," said Styles.
The singer said one has to be honest and truthful when he they are writing, reported Femalefirst.
"When I felt comfortable with these guys straight away, that's when I knew who I want to make the album with," he added.
