David Guetta and Justin Bieber's 2U is Number 1 on this week's Official Trending Chart

Plus listen to the Top 20 songs trending in the UK this week, including Little Mix, Alma and Katy Perry.

Justin Bieber finds himself with the top trending song once again this week - this time with his new David Guetta collaboration 2U.

The track enters straight in at Number 1 on the UK's Official Trending Chart, which is based on a songs' movement up the Official Singles Chart. 

It's Guetta's first appearance at the top of the trending Top 20 since the chart was launched in February 2016, while it's Bieber's second this year following his guest spot on DJ Khaled's Be The One.

Over on the Official Singles Chart, 2U is on course to be this week's highest new entry, currently at Number 3 in the latest sales flash. It's set to give Bieber his 14th Top 10 in the UK and Guetta's 22nd.

Meanwhile, Little Mix's Power ft. Stormzy leaps up the Official Trending Chart following the unveiling of the song's music video, while Ariana Grande's cover of Somewhere Over The Rainbow also makes a strong entry. The track was put out after her One Love Manchester concert, with all profits from the release going to the We Love Manchester Fund. 

Rising star Alma also impacts this week's Official Trending Chart, her latest single Chasing Highs is close to entering the Official Singles Top 40 this Friday, as is DJ Khaled and Drake's new single To The Max.
