Rammstein - Deutschland

You do need a bit of an understanding of German history and to be able to understand German (or just look up a translation) to get the full impact, but holy shit, this video is absolutely insanely good and impactful.
Cliff notes version: the song is about the angst of growing up in a country with one of the most violent and bloody pasts of any of the modern powers, including being responsible for what is generally seen as the most horrific act in our species' history. The lyrics talk about wanting to love and be proud of one's homeland, but being unable to in Germany's case because of everything that has been done in her name.
The video, meanwhile, flips through German history from the Roman defeats at Magna Germania in the early first century AD through to the RAF terrorist attacks near the end of the Cold War. It is an incredibly well done video and there is so much to see in pretty much every scene. I have never been this impressed with a music video before - it is truly unique.
Kill 1 man: You are a murderer. Kill 10 men: You are a monster.
Kill 100 men: You are a hero. Kill 10,000 men, you are a conqueror!
