Lyrics:

So many things
That you still want to see
Even if you know
The best in life is free
You can run away
And think you'll find the treasure
I can ease your pain
And give you all the pleasure
X 2

If you use the key of life
You can open every treasure
Don't have to go around the world
Just go inside , it's in your heart
If you use the key of life
That's the way you'll feel the pleasure
You won't get it somewhere else
Just go inside , it's in your heart
X 3
