>Does Zonda/Olga's theme from Eden's Party (the background theme in the link below) appear in game?
Don't think it does. The CDs have plenty of unique BGMs and vocal tracks. Look at Isola's CD, for instance.

People say Zonda is emotionally dead, but listening to this, she sounds quite emotional. She's coy, she's surprised, she's happy and sad, she even giggles a few times. I guess maybe how she behaved in GV2 was a coping mechanism or something.
