Music can be streamed from the cloud to iOS devices as Google Music Beta is now accessible in iPhone, iPad and iPod touch.
Google Music, which rivals Apple’s iCloud and Amazon’s Cloud Player, allows users to stream music stored in their Google locker account to iOS devices with the help of iOS-specific HTML Web interface.
Unlike Apple’s iCloud, where music has to be downloaded on demand, Google’s Music service is a true cloud-based solution, which streams music from cloud.
To get to Google Music Beta Web app on the iPhone, you need to enter music.google.com in your Web browser.
However, Apple has a huge gamut of music available for purchase. Google Music doesn’t just have a small store, you can't add any songs to Google Music from this app, only listen to those you've uploaded from a computer.
