Mserv is a jukebox-style music server designed to play MP3, Ogg, etc. (configurable) files based on ratings of users who are logged in to the system. It includes features such as searching, filtering, biased random play, queuing, talking, online and off-line track editing, and a standardised TCP protocol. This allows for a variety of interfaces including a built-in telnet interface, a command line program for scripting, a Perl-based Web client, and many 3rd-party GUI front ends.
