English track names are taken from
.NSF playlist; Japanese track
names are taken, where possible,
from "LAGRANGE POINT
SOUNDTRACKS RETURNS" (EMCA-0021)
The original 1991 soundtrack album for the game, simply called
Lagrange Point, includes the Japanese names and credits for tracks like "Bubbles of Light" that are not found on the
Returns rerelease (for copyright reasons), and some different Japanese names as well (the song called "Opening Theme (Opening)"* on
Returns was indeed called "Theme of Isis (Opening)"** on the original album).
From the original album, the composer of "Within the Deep Darkness" (or "Inside Deep Darkness" in the NSF) is 中村 憲司, most likely romanized as "Kenji Nakamura". The composer of "Bubbles of Light" is Tadashi Sawashita (澤下 禎). Finally, the composer of "Relaxed Atmosphere" (typoed as "Relaxed atomosphere" on the album!) is 川本 真, which is either "Shin Kawamoto" or "Makoto Kawamoto".
