R.Kelly - The World's Greatest

Yeah,Uhh...
Uhh...
Yeah..
It's the worlds greatest, Yo,
It's the worlds greatest, Come on,
Worlds Greatest, Ever

I am a mountain
I am a tall tree
Ohhh, I am a swift wind
Sweepin' the country
I am a river
Down in the valley
Ohhh, I am a vision
And I can see clearly
If anybody asks u 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
I'm the worlds greatest
And I'm that little bit of hope
When my backs against the ropes
I can feel it mmm
I'm the worlds greatest

I am a giant
I am an eagle
I am a lion
Down in the jungle
I am a marchin' band
I am the people
I am a helpin' hand
And I am a hero
If any
