Where do I start? The Kindom Hearts songs are automatically on my list. From This is the One, my faves are: Come back to me, Merry Christmas Mr. Lawerence-FYI, This One (crying like a child), and On and on. From Exodus: Exodus 04, Hotel Lobby, Animato, کریملن Dusk, and About me. No, I couldn't pick just one. I'll listen to the other albums once I learn Japanese!
Sanctuary, Passion, Hikari, Simple and Clean, کریملن Dusk, This is Love, Blue, Dareka No Negaiga Kanaou Koro, One Night Magic, Boulevard of Broken Dreams [cover], Making Love, and Colors.
