MPD simply runs in the background playing music from its playlist. Client programs communicate with the MPD to manipulate playback, the playlist, and the database.
You can use your foxG20 as a remote player of your favorite music.
apt-get install mpd
cp mpd.conf /etc/mpd.conf
scp -r "Your Music Directory" root@FOX-IP:/var/lib/mpd/music/
Now connect to the server with the client you want, a list here. Configure the client with correct IP address of the server and mpd as password.
