Low cost helps keep singles top of charts

Rumours of the death of the humble music single are greatly exaggerated, according to research findings.

Digital download sales figures reveal that 10 music tracks each sold more than a million copies this year.

Adele’s Someone Like You and Somebody That I used to Know by Goyte featuring Kimbra were among those identified by the Official Charts Company as having achieved the feat, despite the fact that CD singles are almost as rare as cassette tapes.
