Watch Samsung Galaxy S4s get their groove on doing the surround thing in a Group Play demo

With the Galaxy S4 Samsung is shipping something it calls Group Play, which it demonstrated for us back during the official unveiling. It essentially allows one master device to control a few others, creating group music playback with all the makings of a surround sound system, but also works for pics and vids, too.

The feature is accompanied by playlists creation and sharing, visualizations, and so forth niceties for enhancing the Group Play effect. Now that Galaxy S4 handsets are already out and about, it's no surprise that we are getting live demos of the functionality, and it is coming to other Samsung gear, too, so check out the video demonstration below.
