FF theme songs

Hi all,

I am interested in compiling all the final fantasy theme songs from all games. Outside of Leona Lewis's from FF13 (the english version), I'm a little stumped. If anyone knows them or where to locate them (both english and japanese if able) I would be very thankful. Regular internet searches haven't given me what I have been looking for.

if u count Kindom Hearts in:
Utada Hikaru - Hikari (in english: simple and clean).. in the game its a remix
And i believe for KH2 Utada Hikaru - passion (english: sanctuary)... i dnt have KH2 myself :)

Besides those i have no idea :P

Leona Lewis... Why Square, why...

Final Fantasy VI - Aria di Mezzo Carattere

Final Fantasy VII - One Winged Angel

Final Fantasy VIII - Eyes On Me

Final Fantasy IX - Memories of Life

Final Fantasy X - Suketi De Na

Final Fantasy X2 - 1000 Words (I think).

thanks all.
