Greatest Hits is the band's best-selling album to date, with total sales of over 25 million copies, making it one of the best-selling albums of all time. It reached number one on the UK Albums Chart, spending four weeks at the top and sold consistently well throughout the 1980s, becoming the fourth-biggest selling album of the decade. The single "Under Pressure", which was released the same week as Greatest Hits, also topped the UK Singles Chart.
