These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fan Dumb: Search for any Sabaton song on YouTube. It's pretty possible that most of the comments will be about politics.
Or, in many cases, assuming that all they sing about is Nazis...long story. Crosses over with Moral Guardians when Sabaton was banned from performing in Moscow because of it.
Genius Bonus: More like historian bonus, as the more knowledge about history you have, the more events referenced in their songs you're gonna understand. This pretty much encourages the listener to do a lot of research. A sabaton, by the way, is the metal shoe in a suit of armor.
Poles Love Sabaton: Oh boy, how very much. Thanks to their 40:1, they've found their way into mainstream news and do concerts in museums. Here's the Aesop: when you're a dabbling metaller, and want to quickly and surely gain some notoriety, make a song about brave Polish people. They seem to realise this (heh eh heh heh), as they've now let out Uprising.
Also in Russia, thanks to Stalingrad, Panzerkampf and Attero Dominatus.
Lost in Translation: There is a distinct difference in tone between the Swedish and English versions of "Carolus Rex". The English version is a pretty positive badass-praising album in regular Sabaton-style. The Swedish version is a far more solemn affair, focusing more on the effects of the war on soldiers, civilians and countries, and doesn't shy away from depicting atrocities on either side. The case in point might be the different versions of "1648". The English version praises the defenders of Prague, where the Swedish versions focuses on the greed of General Königsmarck, and the atrocities committed to sate that greed.
Misaimed Fandom - there's potential for that, for obvious reasons. One of their songs is called "Wehrmacht".
Music to Invade Poland to: Sabaton get this a lot. They make bombastic power metal, their vocalist rolls his Rs in a very particular way, and most of their songs are about WW I and II, quite a few of them from the perspective of German forces. Disregard that they have several songs from the perspective of the nations fighting against Nazi Germany as well as definite anti-war anthems, and that their eight minute epic about the Nazi's rise to power is called Rise of Evil. Oh, and the band is Swedish.
All things considered "Music to Defend Poland to" would be a more apt description, considering their Polish fanbase and songs like 40:1 and Uprising.
Joakim Brodén has in interview called the attempts to connect Sabaton's music to Nazi ideology "bullshit" and has questioned why no-one applied the same reasoning to film and asked if Steven Spielberg was a closet Nazi after portraying sympathetic Nazis in Saving Private Ryan.
Case in point: In August 2013 the band were forced to cancel a show in Russia...because a Russian politician thought they were Nazis who intended to desecrate a Russian flag during their concert.
Tear Jerker: I dare you to listen to The Price of a Mile and not get misty-eyed. If you can, your spring needs winding.
Also Cliffs of Gallipoli, with lyrics taken from the Turkish memorial for the Australians who died there.
Oh mothers wipe your tears, your sons will rest a million years
Found their peace at last, as foe turn to friend and forgive
Same with The Hammer Has Fallen.
Also "Purple Heart" and "Light in the Black"; very poignant.
The Final Solution, one of the most amazing power ballads you'll ever hear, is about... Auschwitz.
When freedom burns
The final solution
Dreams fade away and all hope turns to dust
The album Carolus Rex in general can be considered this for patriotic Swedes. Long Live The King is this for everyone.
If you understand Swedish, En Livstid I Krig (A Lifetime of War) definitely does it. The English version not as much, although it still qualifies.
