  • Description: Simple python script which runs as a daemon that displays libnotify notifications with album-art when the mpd song or status changes. Requires python-mpd and libnotify. Use of notify-osd is recommended. If there are notifications from this script pending, their content is just updated, instead of flooding the screen with new ones. Album arts are taken from a specified location, e.g. ~/.covers and downloaded if not found there. Additionally album arts can be saved as jpg-file at a fixed location to be used e.g. with conky (requires pil).

"""Notifies the user when MPD changes

This script polls mpd and sends out a notification using either pynotify or notify-send whenever either the status of
MPD changes or if a new song is being played. In general, it should work fine without any modifications.
Just run it with python If that doesn't work, read on.

Specify the cover art folder, where downloaded cover images will be
stored, below. You can use pycoverart ( to download cover art
for your whole collection if necessary, otherwise, this script will download them when needed. If you want to copy the
art to a particular file location - to display it in conky, for example - you can specify a path to that file on line

Note: The daemonizer apparently doesn't work for everyone. If this is the case for you, uncomment line 58
    - python-mpd
    - python-notify (Optional but highly recommended)
    - python-imaging (Only for conky support)
