Kingdom Hearts has reused songs a lot:
-Simple And Clean appears on the original game
-Sanctuary on KHII
-Simple And Clean appears again on Chain of Memories
-Sanctuary appears again on the DS game, 358/2 days
-Simple And Clean appears for a third time on Birthy by Sleep
hardcore. I will also be disappointed if she doesn't does the theme song for the last game
