Julian Bunetta, One Direction's long time producer, has opened up about the lads' forthcoming new album. 

Speaking to Billboard about the record, which will be their last for an undefined period of time, Bunetta explained that it's more mature and a little more emotionally-charged than their previous offerings:

"There's a song about losing someone that isn't Zayn. There's also a song about the band being on shaky ground and not knowing what the future is. There are songs about love, there's a song that is a little more sexually charged. It's all over the map."

Bunetta also added that this decision for the boys to go on hiatus didn't happen overnight: "There was a lot of them not knowing if they were going to take a break or not, because that wasn't decided just yesterday. There was definitely some of that going on, [but] it wasn't like every day was depressing in the studio."
