Amazon.com has announced plans for an international rollout of Amazon MP3, a DRM-free MP3 digital music store, in 2008.

Amazon MP3 is currently the only retailer that the four major labels are allowing to offer customers DRM-free MP3s. As a result, it can offer over 3.3 million songs from more than 270,000 artists in DRM-free MP3 format.

Amazon MP3 customers are free to enjoy their music downloads using any hardware device; organize their music using any music management application, such as iTunes or Windows Media Player; and burn songs to CDs for personal use.

The company is not disclosing a specific launch timeline for individual Amazon international websites.
