Interesting piece from the article.....
According to the BPI, there were approximately 45 billion audio streams in 2016 - the equivalent of the UK's 27 million households each listening to 1,500 songs over the course of the year.
In December, more than a billion streams were served in a single week for the first time. To put that in context, the UK is now streaming more songs in a week than it did in a month just three years ago.
The above doesn't include youtube and the like.
