Online retailer Amazon.com said on Sunday it will begin an international roll-out this year of its digital music store that offers songs without copy-protection technology. Amazon said it is the only retailer to offer DRM-free MP3s from all four major music labels as well as thousands of independent labels.

Amazon MP3, launched in September 2007, offers DRM-free MP3 music downloads, which now includes more than 3.3 million songs. Most songs available on Amazon MP3 are priced from 89 cents to 99 cents, with more than 1 million of the over 3.3 million songs priced at 89 cents. The top 100 bestselling songs are 89 cents. Most albums are priced from $5.99 to $9.99.
