Recorded music sales - made up of trade value revenue from physical sales, digital sales and performance rights - decreased 18.6% in value on the previous year to $4.98 billion in the U.S. in 2008, according to new figures from the IFPI. The global year-on-year decrease was 8.3% to $18.4 billion.

The global digital increase was 24.1%, to $3.78 billion.

Asia bucked the trend, with total sales up 1% in 2008 ($4.77 billion) and digital up 26.1% ($1.06 billion). But physical sales were down 4.9% ($3.6 billion).

The Latin America market was down 4.7% to $518.6 million, with physical sales declining 10.3% ($430.3 million) and digital up 46.6% ($62.6 million).
