It was confirmed this week that One Direction's latest single, 'Drag Me Down', is the best-selling debut of the year so far in the USA and member Niall Horan has expressed his amazement at the impressive statistic. 

The song earned itself an incredible 349,000 downloads and enjoyed 8.5 million streams during its first week, and Horan told Billboard that he can't believe how well-received it has been so far:

"The reaction to 'Drag Me Down' has been incredible. When we dropped the single we knew we had a good song, but we didn’t expect such a huge reaction. We definitely didn’t think it would become the highest debut on the Billboard Hot 100 chart this year! Again, we need to thank our amazing fans around the world for their constant, unconditional support."

Horan, meanwhile, also recently told BBC Radio 1 that considering his band is now going into its fifth year, this single's success means even more to them: "When we dropped the single we didn't really realise that was the reaction it was going to get. You bring out music and never know what it's [the reaction] going to be like, so to do it five years down the line and to have your most successful single now is pretty good."
