sounds a lot like the graduation ceremony march played during my graduation as a conscript. they kill you with rehearsals in the weeks leading up to it
This has been the anthem of Germany from the Weimar Republic to today (unless you count East Germany, which had its own anthem) The anthem of the Nazi Party itself was Horst Wessel Lied
The song existed before the Weimar Republic so this song cannot be about tyranny. The weimar government wanted to outlaw the first verse because they saw it as "dangerous" which is ironic because there's nothing wrong with saying you prefer your country over all others.
