Niall Horan surprised fans by becoming the first member of One Direction to release solo music (former member Zayn doesn't count) last week.
But how has 'This Town' fared in the charts? Very well, actually.
Reborn to do it, Craig David scores his first No.1 in 16 years
The track is this week's highest new entry after debuting at number nine, while also becoming Niall's first ever solo Top 10.
At the top of the charts, James Arthur hangs on for a second week with 'Say You Won't Let Go' after ending up 27,000 combined chart sales ahead of nearest rival The Weeknd and his Daft Punk featuring track 'Starboy'.
'Say You Won't Let Go' is also the most streamed song of the week after racking up 5.03 million listens over the last week.

We spoke to Arthur about making it back to the top, as well as back into Simon Cowell's good books, and he told us he sent a cringeworthy text to the X Factor boss after reaching No.1, adding: "He probably thinks I'm a f**king weirdo."
Elsewhere, Ariana Grande and Nicki Minaj's 'Side To Side' hops a place to five.
Zara Larsson lands a fifth Top 20 as her new single 'Ain't My Fault' climbs seven places to 16, and Craig David and Sigala's 'Ain't Giving Up' leaps 16 places to 23.
