Listen to the Top 20 songs making a big impact this week, including Matt Terry's collaboration with Enrique Iglesias and Sean Paul.

Louis Tomlinson new single Back To You enters straight in at Number 1 on this week's Official Trending Chart.

The track, which features rising star Bebe Rexha, tops the list of tracks making a big impact in the UK this week following its release last Friday.

Back To You is on track to debut inside the Top 10 on this week's Official Singles Chart, currently at Number 8 in the latest sales flash. The is Louis' second release after last December's Just Hold On ft. Steve Aoki, which peaked at Number 2.

If it holds within the Top 10, it'll mark Bebe's third, following 2014's Take Me Home (with Cash Cash) and last year's Martin Garrix collaboration In The Name Of Love. Her uncredited appearance on David Guetta's Hey Mama ft. Nicki Minaj and Afrojack also peaked inside the Top 10 in 2015.

Meanwhile, a remix of Enrique Iglesias's Subeme La Radio is making waves following its release last week. The new version features Sean Paul and X Factor winner Matt Terry, and is on track to debut inside the Top 20 on this week's Official Singles Chart.

Dua Lipa's latest single New Rules scales this week's trending Top 20, as does Everything Now, the title track and lead single from Arcade Fire's new album in anticipation of its release this Friday (July 28).

Elsewhere, Bruno Mars's Versace On The Floor is on the climb thanks in part to a remix by David Guetta, and two songs from Lana Del Rey's new album Lust For Life are proving popular, the title track and Summer Bummer ft. A$AP Rocky and Carti.

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 single One Dance by Drake, and The Chainsmokers & Halsey's chart topper Closer.

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).
