As more music consumption shifts from purchases to ad-supported free plays, should the Top 40 chart shift along with it? The response from The Official UK Charts Company is a resounding “maybe”.

MD Martin Talbot tells BBC News: “The key task that we’ve been getting to grips with over the past 18 months has been ensuring that - post-download and post-permanent ownership of music - we’re also counting how consumers are consuming their music in other ways ... That’s been relatively simple when people have bought stuff to keep forever. But that’s going to become increasingly more complicated.”
