upmpdcli is a UPnP Media Renderer front-end for MPD, the Music Player Daemon. It supports UPnP gapless track transitions and the OpenHome ohMedia services (including a Radio service to listen to Internet streams).

With a complementary application, it also supports a Linn Songcast Receiver and Sender. The Songcast Receiver function allows you to implement a well-synchronized multi-room system to which any audio (Spotify, etc.) playing on a Windows or Mac system can be forwarded. The upmpdcli Sender/Receiver function also allows multiroom playing from Linux, including of an external input source.

The package also includes a gateway Media Server which enables browsing and playing tracks from external streaming services (at the moment: Spotify, HighResAudio, Qobuz). Audio tracks from the streaming services can be played by an upmpdcli instance or by any other local UPnP renderer.
