Carly Rae Jepsen
Canadian pop star Carly Rae Jepsen has topped the UK's first weekly chart to be based on music streamed via on-demand services such as Spotify.
Last week, the Official Charts Company (OCC) said Ed Sheeran was the most-streamed artist in the UK so far this year.
Martin Talbot, managing director of the OCC, said the chart launch was "a landmark moment for the UK music industry".
