The British Phonographic Industry (BPI) revealed in its mid-year report that streams are up 80 percent — a trend it expects will be bolstered further with Apple Music's entry into the market. Leading streams was Mark Ronson's "Uptown Funk!," which has been played 45 million times via audio streaming this year. Both audio and video streaming showed considerable growth: 2015 has seen 12.5 billion video streams, for a year-on-year increase of 98 percent.
