We recommend that you use the software installation routines of
your distribution to install MPD. Most operating systems have a
MPD package, which is very easy to install.
Installing on Debian/Ubuntu
Install the package mpd
via APT:
apt-get install mpd
When installed this way, MPD by default looks for music in
/var/lib/mpd/music/; this may not be correct. Look at your
/etc/mpd.conf file...
