Sam's comeback and second album campaign is in full swing.

Looks like you've missed Sam Smith in the couple of years he's been away – he's taken his place as this week's Number 1 on the Official Trending Chart.

The singer's comeback single Too Good At Goodbyes tops the 20 songs making the biggest impact in the UK this week, based on movement up the Official Singles Chart.

Sam is on track to secure his sixth Official Singles Chart Number 1 this Friday (September 15), following La La La, with Naughty Boy (2013), Money On My Mind, Stay With Me (both 2014), Lay Me Down feat. John Legend, and Bond theme Writing's On The Wall (both 2015).

Also impacting this week is Logic, Alessia Cara and Khalid's 1-800-273-8255, which should break the Top 40 for the first time on Friday, and TOWIE star Megan McKenna's two tracks – High Heeled Shoes and Far Cry From Love – have been creating a buzz since the broadcast of her new reality show There's Something About Megan on ITVBe. Stefflon Don and French Montana's Hurtin' Me is also making waves and is set to break the Top 40 this Friday.

Finally, new music released last Friday impacting on the latest Official Trending Chart include George Michael's first posthumous single Fantasy, feat Nile Rodgers; Kelly Clarkson (again!) with latest single Love So Soft; former Girls Aloud singer Nadine Coyle with comeback banger Go To Work; and U2 with You're The Best Thing About Me.

About the Official Trending Chart

The Official Trending Chart was launched in 2016 to highlight the hottest new tracks beginning to make an impact in the UK every week.

The Top 20 rundown, published on OfficialCharts.com every Tuesday, based on the first four days’ sales of each chart week, is designed to highlight emerging hits as they begin to scale the Official Charts and build buzz.

The Official Trending Chart ranks titles which are showing week-on-week chart growth, and is the only “new music” chart to reflect audio track sales and streams comprehensively across all services.

Devised by the Official Charts Company in close consultation with labels, retailers and media, the chart since launch has highlighted emerging hits such as Number 1 singles Sign Of The Times by Harry Styles, New Rules by Dua Lipa and Taylor Swift's Look What You Made Me Do.

The chart is designed to help highlight hit singles in their early stages of their growth, in the light of the shift in release strategies of record labels over the past six months. Under “On Air On Sale”, labels have started to release new music for consumers to buy or stream on the same day as those tracks are released to media (including radio stations and TV).
