What was the UK’s song of the summer?

Summer isn’t officially over until 23 September, but as the nights draw in and the temperature drops, it’s time to consider who had the season’s top song.

Depending on who you believe, the title could go one of three ways.

Spotify says Ed Sheeran and Justin Bieber’s I Don’t Care was the UK’s most-played song this summer.

On YouTube, though, the duo were beaten by Lil Nas X’s Old Town Road, while Shazam’s chart was topped by Shawn Mendes and Camila Cabello’s Señorita.

For a decisive verdict, we need the Official Charts Company – who combine sales and streaming figures to come up with a definitive placings for summer’s biggest songs.

And the winner is…… Justin and Ed’s I Don’t Care, which came out on top with the equivalent of 755,000 sales, made up of 90 million streams and 115,000 downloads.

Like the best summer songs, it doesn’t take itself too seriously – the video sees the two A-listers dressing up as ice creams and bananas as they sing about escaping a boring party with their girlfriends.

Musically, the song is built around the Tresillo, or Dembow, rhythm – a syncopated beat that’s become a mainstay of summer songs, from Luis Fonsi’s Despacito to Sheeran’s own Shape of You.
