“If the chart is to be a true barometer of what music is most popular in the UK, it can no longer look solely at purchases – it must also take into account individual listens. Downloads were fully integrated into the singles chart in 2007, but that part of the market has started to plateau while streaming has surged forward. At the start of 2014, the OCC was tracking an average of 192m streams per week; at the start of this year, that had jumped to 360m per week.”
