The "Slow Hands" hitmaker, who hails from Mullingar in Ireland, is set to release his debut solo record later this year, reported Contactmusic.
"I was recording a song a couple of weeks ago, and it's kind of got a Damien Rice feel to it. The producer said to me afterwards 'You have no idea how Irish you sound, when you hear this!'
"He played it back to me and I was like 'JESUS! I sound Irish there!' There's a lot of that stuff on it," Horan says.
"When you listen to it, you'll probably just think I was an emotional wreck.There's some really personal stuff on it. It sounds really stalker-ish, but the way I write is that I could be sitting on a train and see a couple talking to each other and I'd think of a concept around the way that they look at each other or whatever.
"I don't write all of the time from personal experience - sometimes I have concepts," he says.
