Altho I already updated the English tracklist to "semi-localized" a few weeks ago, here are the localized tracks from the Atelier Marie Remake DLC for comparison:
Atelier Iris: Eternal Mana (Atelier Series Legacy BGM Pack)
Atelier Iris: Eternal Mana (Atelier Series Legacy BGM Pack / Organized)
Again, some minor differences between translations. "Little Boy" has become "Flask Boy" in both the DLC and the digital release, the "Far Hometown" digital release is translated as "Longing for Home" in DLC (as well as the OG sound test) and the obnoxious "Tower Forever Gone" has become "Tower of No Return", which sounds much more accurate. Same goes for "Beat of the Rumbling Earth" (Digital) vs "Ground Shaker" (DLC and OG sound test).
All in all, the Series Legacy DLC is almost identical to the original game's sound test, provided by BlazingAbyss here, with minor changes. "A Small Studio" (old) vs "A Small Atelier" (new) - again, more fitting hence the series' nature, or "Legendary Wings" (old) vs "Wings of Illusion" (digital) vs "Phantom Wings" (new), again the latter sounds best in my opinion.
