In June 2014, the Official Charts Company (OCC) started including audio streams in the official UK Singles Chart, recognising their importance as an indicator of current popular trends and tastes in music. From this point onward, the popularity of a single or album track can be measured by both sales (which include paid downloads) and streams on officially recognised subscription and ad-funded on-demand services. Although the OCC added these figures to the chart in July 2014, they started compiling them in May 2012 through the Official Audio Streaming Chart. They are taken from on-demand audio streaming services such as Spotify, Apple Music, Google Play Music, Deezer and Tidal, all of which are members of the Entertainment Retailers Association (ERA).
As of June 2016, the most streamed song in the UK was "Sorry" by Justin Bieber, the first song to pass 100 million streams. By September 2016, it had been joined by two other Bieber songs: "Love Yourself" and "What Do You Mean?" as well as "One Dance" by Drake (the first song to achieve 100 million streams in a calendar year).
The song with the most streams in one week is "Shape of You" by Ed Sheeran in chart week ending 19 January 2017 with 13.4 million. In the same week "Castle on the Hill" also by Sheeran became the only other song to get more than 10 million streams in a week with 11.07 million.
In July 2014, the OCC announced that "Pompeii" by Bastille was the most streamed song in the UK with 26.6 million streams. "Cheerleader" by OMI was the most streamed song of 2015 with 71.7 million and "Rather Be" by Clean Bandit featuring Jess Glynne was the most streamed song in 2014 with just short of 40 million.
