Amazon has debuted a new piece of desktop software dedicated to music. The new Cloud Player is part of Amazon's mission to bring its music service "everywhere" and is extremely focused on the music. Cloud Player already existed as a web app, but lacked some of the features that come with a dedicated desktop app.
For instance, the desktop software is capable of storing music offline, something the web app simply couldn't do. The Cloud Player app is also capable of scanning for stored music that hasn't been added to a user's locker. A Mac version is currently in the works and Amazon advises that Mac users "stay tuned."
