Songfacts®:

• This uptempo track from One Direction's debut album, Up All Night, was written by Tom Fletcher, the co-lead vocalist and guitarist of McFly. The English band were one of the top-selling groups in the mid 2000s in their home country, clocking up seven #1 singles between 2004 and 2007. Tom also co-wrote three UK chart-toppers for another pop band, Busted.
• Tom Fletcher has been a fan of One Direction from their very early days. He recalled to Billboard magazine: "When I was in the studio with them, I was like, 'Guys, you don't understand, you're going to be massive,' They're all awesomely talented guys, stupidly good-looking of course, as well. Young. They've got everything. They've got the whole package. But none of them realized it. They're all very humble and down to earth. It just reminded me of exactly of how we were like when we started."
• During a March 2026 Captal FM interview, Niall Horan was asked which One Direction song he hated performing. He admitted "I Want" was not a favorite.
  
  "I wouldn't say I hated performing it," he said. "It's more in hindsight that I hated it. I didn't mind it, I loved it. But I just think with all the music that we had on the back end, the last two or three albums were in my eyes very, very good and I loved all the songs."
