mympd should be system user & group instead of normal user & group

[CultofRobots]

add "-r" or "--system" to lines 54 & 56 in mkrelease.sh
54: [ "$?" = "2" ] && sudo groupadd -r mympd
56: [ "$?" = "2" ] && sudo useradd -r -g mympd -d /var/lib/mympd -s /usr/sbin/nologin mympd

From an organizational standpoint it's better to use a system account for a service as opposed to a normal user account. Will also keep mympd out of the login dialog.

from the man page:

-r, --system
Create a system account.

System users will be created with no aging information in /etc/shadow, and their numeric identifiers are chosen in the SYS_UID_MIN-SYS_UID_MAX range, defined in /etc/login.defs,
instead of UID_MIN-UID_MAX (and their GID counterparts for the creation of groups).

Note that useradd will not create a home directory for such a user, regardless of the default setting in /etc/login.defs (CREATE_HOME). You have to specify the -m options if you want
a home directory for a system account to be created.
