This is not a real client, this program only launches KDE notifications every time song changes. Also shows nice album arts, if you have them. You can also specify a client to launch if you click on the notification.
tar -xvf notify-v1.tar.bz2 cd notify/build cmake .. make sudo make install
You might need to copy file mpdknotifier.notifyrc to /usr/share/apps/mpdknotifier/mpdknotifier.notifyrc or whichever directory your knotify4 daemon uses. Then you might need to restart the knotify4 daemon helped me.
sudo mkdir /usr/share/apps/mpdknotifier sudo cp mpdknotifier.notifyrc /usr/share/apps/mpdknotifier/mpdknotifier.notifyrc sudo killall knotify4 knotify4
Also, you need to create file ~/.kde4/share/config/mpdknotifierrc with following content
[General] MPDHost=*your MPD host* ie. localhost MPDPort=*your MPD port* ie. 6600 MusicDir=*your music directory* ie. /home/kuba/music/ ClientName=*name* ie. ncmpcpp ClientCmd=*command to launch your client* ie. konsole -e ncmpcpp as
