Vicious MPD widget not displaying the artist and song title

Question

EDIT: This thread can be closed now. It turns out Clementine doesn't support mpd and I'm now running ncmpcpp and the widget shows the artist and song title.
I have trouble getting the mpd widget running in awesome wm, it will only display "N/A - N/A". I've read the wiki and done a lot of googling but I can't figure out what I'm missing.
Here's my rc.lua

Answer 1

Hi,
If the songs were purchased from itunes, I suggest that you delete the tracks from your itunes library and move to trash (providing you live in a country that permits redownloading). See http://support.apple.com/kb/PH12283.
