Music streaming on services such as Spotify is to be included in the singles chart from next month after bosses behind the countdown finalised a deal.
Playing songs through on-demand services will feature in the Official Singles Chart for the first time on Sunday, July 6.
The Official Charts Company will weight the streaming so that 100 plays amount to one physical sale to draw a difference between shelling out specifically for a track and merely choosing to play it as part of a general service.
So far this year the average weekly figures volume of streaming is 70 times greater than the combined sales of downloads and physical singles.
Controversially, it marks the first time that chart positions could be affected without music fans actually making a purchase. On average the number of weekly streams for 2014 is currently at 228 million, while the level of single sales trails significantly at 3.2 million.
