R.Kelly-The World's Greatest

Who´s the worlds greatest
Who´s the worlds greatest
The worlds greatest

I am a mountain
I am a tall tree ohh
I am a swift wind sweeping the country
I am a river down in the valley ohh
I am a vision and I can see clearly

If anybody asks you who I am
Just stand up tall
Look 'em in the face and say

<Chorus>
I'm that star up in the sky
I'm that mountain peak up high
Hey I made it
Mmm..
I'm the world's greatest
I'm that little bit of hope
When my backs against the ropes
I can feel it
Mmm..
I'm the world's greatest
the world greatest,
the world greatest, forever

I am a giant
I am an eagle ooh
I am a lion
Down in the jungle
I am a marching band
I am the people ooh
I am a helping hand
I am a hero
