How to use Amazon Cloud Player | Web | Playlist | Macworld: The Cloud Player doesn’t support the playback of these tracks on an iOS device. This is not a technical issue, however. Rather, Amazon is looking for browsers identified as Mobile Safari. When it receives a request from just such a browser, you see a message that your browser is not supported. This is not a limitation of the iOS device, but rather Amazon’s unwillingness to stream this content to iPhones, iPod touches, and iPads.
The proof is in an alternative browser. Download a copy of another iOS browser—Atomic Web Browser or iCab Mobile. Each of these browsers allows you to change the transmitted identity of your browser. If, for example, you choose to identify the browser as Safari Desktop, you can access the contents of your Cloud Drive. Once you do, simply tap a track and then tap the triangle menu icon. From the menu that appears, select Download. A QuickTime window will appear, and your track will play. Regrettably, there doesn’t seem to be a way to play a series of songs with one command. Rather, you must play each song using this tap-and-download method.
