THE British band Coldplay had the world's best-selling album of 2005, according to new figures.
The band's third album, X&Y, sold 8.3 million copies.
Mariah Carey's The Emancipation of Mimi sold 7.7 million copies, and rapper 50 Cent's The Massacre shifted 7.5 million.
Overall, global music sales of "physical" and digital music combined were down 3 per cent, according to the International Federation of the Phonographic Industry (IFPI) report. But revenues from digital music sales almost tripled last year, from 230 million in 2004 to 633 million in 2005.
Single sales - digital and "physical" - increased by over 75 per cent globally.
Singles are now largely a digital format, with digital sales accounting for three- quarters of total single sales, compared to 45 per cent in 2004. CD album sales fell by 6 per cent in value.
"Physical music sales declined again for a combination of reasons, including digital and physical piracy, competition from other entertainment products and the shift in consumer spending to online and mobile," said IFPI chairman John Kennedy.
"In 2006, we expect to see continued growth online and more innovative mobile services attracting music fans into the legal digital market. All our member record companies are now aggressively licensing and marketing music in digital formats."
