vimpc is a curses-based client for the Music Player Daemon (mpd) that draws inspiraton from vi/vim. It supports a vim-like rc file, mappable key bindings, normal/ex modes, counts, searching, a music library, directory navigation, playlist editing, and comprehensive help, is highly configurable and customizable, and more. It is written with the intent to make vi users feel at home when using mpd, but is also intuitive and very usable by non-vi users.
MPDisco is a Node.js-based music server built to let teams and groups control a single music player together. Accessing an MPDisco server puts each user, after logging in, in a rotating DJ queue. Each user will be given one hour (by default) to control the playlist and music player.
Moosic is a music player that focuses on easy playlist management. It consists of a server process that maintains a queue of music files to play and a client program which sends commands to the server. The server continually runs through its playlist, popping items off the top of the list and playing each with an external program. The client is a simple command-line utility which allows you to perform powerful operations upon the server's queue, including the addition of whole directory trees, automatic shuffling, and item removal according to regular expressions. The server comes configured to play MP3, Ogg, MIDI, MOD, and WAV files.
