Gbemol allows you to use MPD with a userfriendly interface. Features include an easy-to-use, tag-oriented library browser, a two mode playlist, cover art support (APIC tag only, for now), system tray icon docking, song, album and artist information.
Music Player Daemon is a server that allows remote access for playing audio files, streams and managing playlists. The daemon is controlled through a client which need not run on the same computer mpd runs on.
