I can't say why right now, but it's insane to have a video directly talking about the Psycho Soldier Arrangement in Smash Bros. The idea that "We need to be careful to not detract from each player's own past experience with the piece" is something that can be applied not only to the music, but to the series as a whole, as so much of it is about not only representing the best version of a character, place, song, or franchise, but also our collective memories of them.
