Simple and Clean

Simple and Clean is the theme song of Kingdom Hearts, written and sung by Utada Hikaru.

"Simple and Clean" plays during the ending videos of Kingdom Hearts, Kingdom Hearts: Chain of Memories and Kingdom Hearts Re:Chain of Memories.

In the recent Japanese December commercial for Kingdom Hearts Birth by Sleep, the music played was "Hikari", the song's Japanese version.

Other Versions
Hikari is the original, Japanese version of "Simple and Clean". It was used in the Japanese version of Kingdom Hearts, Kingdom Hearts Final Mix and in the Japanese version of Kingdom Hearts: Chain of Memories.

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
