It works well, you have nothing in the way on your desktop and don't use a lot of resources.
You need to install: promoe (gui-client), python-xmmsclient, xmms2-plugin-m3u, xmms2-plugin-mpg123 and xmms2-plugin-pls, along with xmms2 if you want GUI that can play mp3
Might be very good - I dont have time to command line to play MP3s - GUI please !
