It's Man's World的詞曲作者及演唱者並未明確透露，但有網上流傳的版本。以下是其中一個版本的歌詞：
Verse 1:
It's a man's world, yeah
But it wouldn't be nothing
Without a woman or a girl
We might as well call it
Half a world, yeah
Chorus:
But it's not just men
Who can make a change
It's a woman's world
And we can make it better
Verse 2:
It's a man's world, yeah
But we need to understand
That we all have a part to play
And we can make it better
Chorus:
But it's not just men
Who can make a change
It's a woman's world
And we can make it better
Bridge:
We might as well call it
Half a world, yeah
But let's not forget about the girls
Who are making a difference
In their own way, yeah
Chorus:
But it's not just men
Who can make a change
It's a woman's world
And we can make it better
Make it better, yeah
