To begin, you’ll need to register your Sonos system first to begin using Cloud Player and install the Sonos controller on your device. But if you haven’t tried any of Sonos’s awesome speakers, you can always do your shopping via Amazon. “Our goal is to enable customers to enjoy all their music, wherever they are, and on any device. Launching on Sonos today is an important part of that strategy, as our customers have been asking us to add Sonos to the list of compatible Cloud Player devices ever since we first launched Cloud Player,” said Steve Boom, vice president of Digital Music for Amazon.
