Amazon has launched a service called for the Web and Android phones, offering 5GB of free via Amazon Cloud Drive for your existing music collection. You can upgrade with options ranging from 20GB for $20 per year up to (for those who have too much money on their hands) a terabyte for $1000 per year. Upload your existing music files to Cloud Drive, and Cloud Player will stream them to your PC over the Web, or to your Android phone via the Amazon MP3 app. Android users also have the option of copying the files to their SD Card to save bandwidth and avoid streaming problems.

Earlier this month, Google launched , which works like Amazon Cloud Player but includes a desktop app. While in beta, the service is free. Final pricing has not been announced.
