Meghan Trainor enters charts on streaming alone

Meghan Trainor's single is not released for purchase until Monday

US singer Meghan Trainor has become the first act to enter the UK top 40 based purely on streams of her music.

She entered the singles chart at number 33 with All About The Bass, three months after rules changed to count streamed songs towards chart positions.

The track racked up 1.17 million streams over the past week. The song is not available for download or physical sale until Monday.

Meanwhile Jessie J landed her third UK number one single with Bang Bang.

The collaboration with Nicki Minaj and Ariana Grande, went straight into the top spot.

It was announced in June that songs played on streaming services would count towards the UK's singles chart - with 100 streams equalling one single purchased. Before that only sales and downloads counted towards chart positions.

Martin Talbot, chief executive of the Official Charts Company, said Trainor had "broken new ground".

The catchy "body positivity" anthem has already been a chart-topper in the US and is expected to be a strong challenger for the UK's number one spot next week.

But for now that honour belongs to Jessie J's Bang Bang, the first track from the singer's new album Sweet Talker.

Bang Bang knocked Sigma and Paloma Faith's collaboration Changing off the top spot.

"I'm going to celebrate every minute of it, I might even go bowling," said Jessie J.

Cilla Black just missed out on the top 40 after the re-release of her 1964 number one hit Anyone Who Had A Heart finished at number 47.

The song had re-entered the midweek chart at number 40 in the wake of the success of Sheridan Smith's ITV three-part drama Cilla, which will conclude on Monday.

In the album chart, British indie band Alt-J went to number one with This Is All Yours.

The album is the band's follow-up to their Mercury Music Prize-winning debut, An Awesome Wave.
