The Official Charts Company said "the time is now right" to add music streaming to the UK singles chart for the first time.
Chief executive Martin Talbot said:
Audio streaming has grown at an extraordinary rate over the past year - and the time is now right to take this important step.
Just as it [the Official Singles Chart] has evolved through the years to reflect the most popular music in the UK, from 10-inch to seven-inch, vinyl to cassingles, CD singles to downloads, this is the latest stage of that progression.
Music streaming on services such as Spotify and Napster will be included in the UK singles chart from July 6.
The Official Charts Company will weight the streaming so that 100 plays amount to one physical sale to differentiate between buying one specific 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.
Nationwide shoe shop Office has become the latest company to fall victim to a cyber attack, forcing the retailer to warn its customers to change their account passwords.
The high street chain confirmed its online security had been breached, following similar attacks on eBay and Spotify, but said customers' financial data had not been compromised.
The retailer has emailed users urging them to change their login details on other sites.

Last week eBay announced that a breach in their security had given hackers access to more than 100 million users while Spotify updated its Android App after a user account was deemed to have been compromised.
