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.
