**You must own a Synology NAS to run this app, and be running the latest Audio Station 6.0.0 package to get the complete set of features** DS audio allows you to stream music stored on your DiskStation with your Android device wherever an Internet connection is available. Better yet, with the offline mode you can listen to songs stored in the device’s local memory for when no network connection is available. You can browse music by albums, artists, folders or genres, create your own playlists or share them with your friends, and even rate your music! And if you have dedicated stereo speakers at home, DS audio can also become a remote control to stream music to them.
