Recently the Amazon Cloud Player app was released for Roku. This allows you to listen to tunes you’ve purchased or uploaded with the Amazon Cloud Player Scan and Match feature on your home theater system.
Go to the official Roku site and install the Amazon Cloud Player app. It’s easier to do it this way than find it in the Channel Store.
After it’s installed, fire up your Roku and launch Amazon Cloud Player. You’ll get a code to link your Amazon account with the Roku app.
After linking your account successfully you can start listening to the tunes in your Amazon Cloud Player on the Roku. Just like with other devices, you can browse navigate through Playlists, Albums, Songs, or Search.
The app works essentially like it does on the Kindle Fire, iOS and other Android devices. When playing a song you can can control playback, skip to the next or previous tune, and it has a Shuffle feature too for parties.
