As CNN reports, Amazon has launched a cloud player-- an online database that lets you access your music library (or any digital files) from anywhere. With the service, you can upload your music to Amazon's Cloud Drive, and they'll host it for you, which means you won't have to keep it on any physical hard drive. And it doesn't have to be music purchased from Amazon. It can be any digital file: photos, documents, etc. You can access the music on your Cloud Drive through the Cloud Player, which works as a web app or an Android app.

Right now, Amazon is offering 5 GB of free service, or 20 GB worth of Amazon purchases. CNN also reports that Apple and Google are rumored to be working on their own cloud players as well.
