Nearly 10-years after the iTunes Music Store first opened up for business, iTunes remains the market leader in digital music downloads.
According to a research report published by the NPD Group earlier this week, iTunes accounted for approximately 63% of all digital music downloads in 2012. Trailing behind is AmazonMP3 with a somewhat respectable 22% share. While Amazon has a ways to go before even getting close to Apple, the world's largest online retailer has been making significant gains in that regard. In 2011, Amazon's share of the digital music download market checked in at 15%, representing a solid 50% increase year over year.
