More than 200m tracks a week are streamed in the UK

"From the beginning of July, audio streams of music will be counted towards official chart rankings alongside single purchases and downloads.
The Official Charts Company, which compiles the weekly chart, said it was a necessary reform in light of the growing popularity of digital streaming, with the number of weekly audio streams now exceeding 200m.
This year alone has already seen nine different tracks exceed a million streams in a week, including Rather Be, the No 1 debut by Clean Bandit, and Waves by Mr Probz."
