Top Cloud Services for Storing and Streaming Music
Online music lockers not only back up your music library but also let you listen to it on most any device, anywhere you have Internet access. All three of the services we looked at work on PCs and Macs; mobile device support is more fractured, however.
Amazon Cloud Player

Amazon customers enjoy 5GB of free storage; you can purchase more starting at $20 per month for 20GB. Songs bought through Amazon don’t count against your data cap. Unfortunately, the service has an Achilles’ heel: Amazon’s Cloud Player supports only MP3 and AAC files, leaving you on your own to convert unsupported file formats.
Apple iCloud

Although Apple gives you 5GB of storage space, everything you store in iCloud—photos, documents, music, and more—counts against that quota. An additional 10GB, 20GB, or 50GB costs $20, $40, or $100 per year, respectively.
Google Play

The Winner
In this category we’re declaring a three-way tie. Google Play supports the largest number of codecs, Amazon Cloud Player supports the most platforms, and Apple iCloud is the most natural fit for the iPad.
