PLANiTB made a remix of Simple and Clean and Hikari which is played during the Opening Movie of Kingdom Hearts and Kingdom Hearts Final Mix. This version is faster, shorter and has more of a dance mix feel to it than Utada's original song.
In addition, an orchestral arrangement of Hikari can be heard in Kingdom Hearts and Kingdom Hearts Final Mix in the Opening Menu Cinematic which appears if the player lets the opening menu sit for ten or fifteen seconds.

English Lyrics (Simple and Clean)
When you walk away
You don't hear me say please
Oh baby, don't go
Simple and clean is the way that you're making me feel tonight
It's hard to let it go
You're giving me too many things
Lately you're all I need
You smiled at me and said,
Don't get me wrong I love you
But does that mean I have to meet your father?
When we are older you'll understand
What I meant when I said "No,
I don't think life is quite that simple"
When you walk away
You don't hear me say please
Oh baby, don't go
Simple and clean is the way that you're making me feel tonight
It's hard to let it go
The daily things
like this and that and what is what
that keep us all busy
Are confusing me
That's when you came to me and said,
Wish I could prove I love you
But does that mean I have to walk on water?
When we are older you'll understand
It's enough when I say so
And maybe some things are that simple
When you walk away
You don't hear me say please
Oh baby, don't go
Simple and clean is the way that you're making me feel tonight
It's hard to let it go
Hold me
Whatever lies beyond this morning
Is a little later on
Regardless of warnings the future doesn't scare me at all
Nothing's like before
When you walk away
You don't hear me say please
Oh baby, don't go
Simple and clean is the way that you're making me feel tonight
It's hard to let it go
Hold me
Whatever lies beyond this morning
Is a little later on
Regardless of warnings the future doesn't scare me at all
Nothing's like before
Hold me
Whatever lies beyond this morning
Is a little later on
Regardless of warnings the future doesn't scare me at all
Nothing's like before

Hikari" was assumed to be the theme song of the entire Kingdom Hearts series, as the same orchestral arrangement was heard in the trailers of Kingdom Hearts II, as well as towards the end of Kingdom Hearts II.
