From Andrew Bednarz:
MServ Client is a client for the MServ (http://www.mserv.org/) jukebox music server.
If you use MServ in a common area this app will be useful to you.
If you don't know what MServ is, or don't use it, this app won't be useful.
MServ Client allows you simply see what is currently playing and to play, stop or skip to the next track, and adjust the volume (on a supported server).
