Mopidy is a music server which can play music both from multiple sources, like your local hard drive, radio streams, and from Spotify and SoundCloud. Searches combines results from all music sources, and you can mix tracks from all sources in your play queue. Your playlists from Spotify or SoundCloud are also available for use.
To control your Mopidy music server, you can use one of Mopidy’s web clients, the Ubuntu Sound Menu, any device on the same network which can control UPnP MediaRenderers, or any MPD client. MPD clients are available for many platforms, including Windows, OS X, Linux, Android and iOS.
To get started with Mopidy, start by reading Installation.
