There had plenty of speculation about a similar type of music service being developed by Apple or Google, but Amazon has beaten those two to the punch. Amazon is also allowing customers to store other files, not just music files, meaning that Cloud Drive could become a competitor to cloud services like the popular Dropbox.
Customers who purchase an album from Amazon will be automatically upped to 20Gb. MP3 purchases from Amazon will be automatically stored on the Cloud Drive and will not count against the 20Gb total.
Amazon Cloud Drive is also included in the Amazon MP3 Android app. If you’re an iPhone/iPod/iPad user, it's unlikely that Apple will give this iTunes competitor the green light.
In recent years, Apple has been the dominant player in the digital music market. Meanwhile, more recently Google’s has been working on its own online music service but, for now, Amazon has grabbed the lead in the cloud-based music world with it's new service.
