Apple announced this week that their iTunes store has now sold over 10 billion songs since its launch in 2003.
The 10 billionth song was 'Guess Things Happen That Way' by Johnny Cash and was downloaded by an American music fan who was awarded a 10,000 dollar iTunes gift voucher.
However the news comes at a time when there are signs that the overall music download market may be shrinking.
According to digitalmusicnews.com market research company NPD have found that the number of people paying for music downloads in the US actually decreased between 2008 and 2009.
It's thought that the drop could be due to older customers who have tried downloading but then gone back to CDs.
