He is a current member of the four-piece (former five) band One Direction, formed in 2010) and currently on hiatus. Aside from being a singer, Horan is a songwriter, all-round musician, model, golf manager, social influencer and philanthropist.

In 2010, Horan auditioned as a solo contestant for the British X-Factor. Prior to this, Horan performed as a singer across Ireland including a role as a support act for Lloyd Daniels in Dublin. After being eliminated as a solo performer in one of the early stages of the show, Horan joined four other solo contestants to form One Direction. As a group, they ended up third in the competition and got signed by judge Simon Cowell's record label SYCO. The band rose to immense popularity from the very start. In their prestigious career, they have released five albums, embarked on four world tours, and won several awards.

Following the band's hiatus in 2016, Horan signed a recording deal as a solo artist with Capitol Records. His singles "This Town" and "Slow Hands" from his debut studio album Flicker (released in October 2017) reached the top 20 in several countries. The album debuted at number one in Ireland, the Netherlands and the United States, as well as charting within the top three in Australia and the UK.

In August 2017, two months before the release of his album and with only two songs officially released, Horan announced his first solo tour, the Flicker Sessions. The 20-show tour sold out instantly and saw Horan perform songs from his unreleased debut album in intimate venues across the globe.
