I just looked in my liner notes to the Japanese TDS, on both occurrences of Dead Souls, it is listed as Dead Souls (Bonus Track). Also, the blue for the credits to Dead Souls is a shade lighter than the rest of the blue (a slightly less deeper shade of mushroom blue, i suppose). It just doesn't... fit. Same way "reptilian" is in a different font than the rest of the font on the japanese FDTS (look closely and you'll see on both the disc and the track listing).
