Great reaction, If you want another Blind Guardian Tolkien themed song try Nightfall live at Wacken 2011 or Rockpalast 2016. Crowd goes crazy singing it. Its about the downfall of the Noldor and their flight from the blessed lands after the Silmarils were stolen.
Sorry, but do more BG songs, cause make sense. At least as you both like melodic metal. Can´t be better... Would suggest something like Mordred´s song.
