which one is better Passion or Sanctuary?

i would say sanctuary because i can understand it. Although passion is fun to sing when you understand what it means. passion has more.....idk but it has a certain loudness to it and makes a great song to play when your playing video games. (especially kh2)!!!!

I guess that all depends on how much you adore the Japanese language.

Musically, they're the same song...in fact Utada wrote Sanctuary before Passion but Passion was released first.

passion

why not have both
