One thing two songs... *boogles*

Anyway, first off. Does anyone know the name of the song that plays in FF8 during the conversation between Quistis and Rinoa in the Galbadia Mansion?

And a song in FFX called Illusion. I never heard it during the game (outside of the Luca Theatre anyway), and the name isn't anywhere on the OST last time I checked. Is there a different name for it?

Thanks in advance. ^_^
