Amazon today launched its new Cloud Drive online storage service, alongside a new Cloud Player that allows users to play back music stored using the service. The Cloud Player supports both MP3 and AAC files, and can be accessed from any PC or Mac, as well as from Amazon’s MP3 app for Android; purchases made on Amazon’s MP3 store can be automatically added to the service and do not count against the user’s storage limit. Amazon is offering 5GB of storage for free, with higher storage capacities priced at $1 per GB per year. Notably, customers who purchase an album from the Amazon MP3 store receive 20GB of free storage for one year. The service makes Amazon the first among itself, Google, and Apple with a cloud-based music service; Apple is reportedly working on a such a service for introduction later this year.
