We have a favourite composer thread, but we don't have a thread for individual soundtracks (none recent that I found). So which soundtracks do you love?

I like:
The Hobbit (GC, PS2, XBox)
Mega Man X4 - X6
Mother 2 (otherwise known as Earthbound)
The Legend of Zelda - the 3D games' OSTs are my favourites
Final Fantasy I, VIII, and X
Castlevania: Legacy of Darkness
