"British music fans are increasingly opting to buy their albums as digital downloads, but overall sales declined in the third quarter.
The music industry continued to suffer from the decline in sales of physical formats such as CDs, according to figures from the Official Charts Company for the three months to September, and the total market was down 11.4% year on year to 21.8m units sold.
Digital downloads accounted for 28.2% of all UK albums sold in the third quarter, up 24.2% on the previous year, to reach 6.1m.
Sales of physical albums, including CD and vinyl, were down 20.5% year on year to 15.5m units."
