Oh no, it's spreading, WHAT WILL WE DO?!?!?! WHO WILL SAVE THE WORLD NOW.
Yeah, if you haven't already, you should try out Blind Guardian and Kamelot. I got my start in this genre through Sabaton and those two bands (for the former, I recommend the song "Another Stranger Me", and generally anything off of that album; for the latter, "Veil of Elysium", and their albums The Black Halo and Haven are fantastic). It's pretty incredible.
