KMP is an Music Player Daemon client that uses the QT GUI toolkit so it will comfortably fit in with your KDE desktop, although only QT is required. MPD is a daemon that runs in the background and accepts connections from clients which can then tell MPD what to do. KMP aims to be a full featured and easy-to-use client. KMP will allow you to browse the server's collection, add songs to the playlist, change the volume, etc.
