For the Reunion has to be my favourite. I have downloaded it while I am waiting for my soundtrack to arrive from Hong Kong, and play it over and over again. I just close my eyes and let myself feel like I am floating and spinning in the air. I can feel evilness in it as well as innocence, very much like Kadaj is; yet I also find it haunting.
Another one that I love is Beyond the Wasteland.
All the music is good to be quite honest, and I enjoy the old stuff re-done from the game because it takes me back to when I first started playing it. My favourites of those have to be Aerith's theme and Tifa's theme.
