I'm divided on the issue. While the Empire is clearly a fascist, genocidal regime, it's still just a fairy tale regime where little actually violence and horror is being shown. And it's just a theme music, after all, saying “here come the badass guys.” If I could, I would probably play the music myself when I greet my fellow programmers every morning. It's not like they used mock hitler salutes or played the Horst Wessel song. Then I'd give them the boot.
For active troops, I'd totally rule out that march, though.
