Correct.

# netstat -putan | grep mpd
tcp        0      0 0.0.0.0:8000            0.0.0.0:*               LISTEN      721/mpd

Nos I never though of grepping 6600:
         
# netstat -putan | grep 6600
tcp6       0      0 :::6600                 :::*                    LISTEN      1/init

Moreover:

# lsof | grep 6600
systemd      1            root   52u     IPv6              12676        0t0        TCP *:6600 (LISTEN)

# systemctl status mpd-socket
● mpd-socket.service
   Loaded: not-found (Reason: No such file or directory)
   Active: inactive (dead)

I'm faily noob with respect to systemd, so I might be missing some other tool to check stuff here.
