Demystifying Amazon’s Cloud Player - Lauren Goode - Product Reviews - AllThingsD

Excerpt from a review of Amazon's alternative to iTunes

"For this week’s review, I tested Amazon’s Cloud Player, a Web and mobile app that automatically recognizes the music files you’ve already purchased, adds those same tracks to your Amazon cloud account, and then lets you stream those files on up to 10 devices, even if you got the music from iTunes, from a CD, or some other source.
Amazon is able to do this in part because it recently obtained the music rights from the four major record labels in the U.S. The service is now more comparable to iTunes Match, Apple’s cloud-based service, which similarly scans and matches non-iTunes music files on up to 10 devices."
