/*
This script has been forked from the following, with some tweaks / hacks added as it no longer works
http://greasyfork.icu/de/scripts/369383-songsterr-print-enabler

An easy way to test the CSS in this script is to emulate the 'print' css media type. To do this,
open 'dev tools' -> 'more tools' -> rendering -> set 'Emulate CSS media type' to 'print'
