Cannot start mpd as systemd service

Question

Hi all,
I have installed mpd. If I run
mpd
from a terminal, then everything is normal; I can open
a client and use mpd. However, if I try to start it as a systemd service I get errors. That is, once I do
sudo systemctl enable mpd
and reboot, then
jorge@flamingo:~$ systemctl status mpd

Here is the mpd config file:
jorge@flamingo:~$ cat ~/.mpd/mpd.conf
music_directory "/home/jorge/Multimedia/Audio/Music"
playlist_directory "/home/jorge/.mpd/playlists"
db_file "~/.mpd/mpd.db"
log_file "~/.mpd/mpd.log"
pid_file "~/.mpd/mpd.pid"
state_file "~/.mpd/mpdstate"
audio_output {
type "alsa"
name "MPD"
restore_paused "yes"
follow_inside_symlinks "no"
Any ideas what I'm doing wrong here?
Thanks in advance.

*facepalm*
Oh dear.. An update fixed the problem indeed, thank you.

You're right.. I just read the wiki more carefully. Indeed, I would like to run it for my user, so systemd is not
the best option for me. But I still have trouble.. The problem is that I can't autostart it the way it mentions
in the wiki. My mpd files are as follows:
jorge@flamingo:~$ ls ~/.mpd
mpd.conf mpd.db mpd.log mpd.pid mpdstate playlists
I tried this as per the wiki:
jorge@flamingo:~$ cat ~/.profile
# MPD daemon start (if no other user instance exists)
[ ! -s ~/.mpd/mpd.pid ] && mpd
but it didn't work. mpd was not running after reboot.
Then I tried /etc/profile:
jorge@flamingo:~$ cat /etc/profile
# /etc/profile
#Set our umask
umask 022
# Set our default path
PATH="/usr/local/sbin:/usr/local/bin:/usr/bin"
export PATH
# Load profiles from /etc/profile.d
if test -d /etc/profile.d/; then
for profile in /etc/profile.d/*.sh; do
test -r "$profile" && . "$profile"
done
unset profile
fi
# Source global bash config
if test "$PS1" && test "$BASH" && test -r /etc/bash.bashrc; then
. /etc/bash.bashrc
fi
# Termcap is outdated, old, and crusty, kill it.
unset TERMCAP
# Man is much better than us at figuring this out
unset MANPATH
export GPODDER_HOME="/home/jorge/Applications/Application Data/gpodder"
# MPD daemon start (if no other user instance exists)
[ ! -s ~/.mpd/mpd.pid ] && mpd
but it didn't work either.
In both cases, if I try to run mpd again from the terminal, I get:
jorge@flamingo:~$ mpd
server_socket: bind to '0.0.0.0:6600' failed: Address already in use (continuing anyway, because binding to '[::]:6600' succeeded)
and then mpd works.
Any ideas on how to startup mpd automatically on boot without systemd?
