I know these lyrics but need to know the artist

I am a powerful woman
I have very powerful needs
I have wonderful ideas
I have quite incredible dreams
My dreams tend to come true
They tend to include you
I sense the world is changing
I guess..... I will change too

We are a powerful people
We have very powerful needs
We have wonderful ideas
We have quite incredible dreams
Our dreams tend to come true
They tend to include you
We sense the world is changing
We guess... we will change too.

We are a powerful people
We have very powerful needs
We have wonderful ideas
We have quite incredible dreams
Our dreams speak of freedom
Freedom speaks from inside
Inside speaks for itself
We've got no reason to hide because

We are a powerful people
We have very powerful needs
We have wonderful ideas
We have quite incredible dreams
Our dreams they will come true
Our dreams they include you
We know the world is changing
We know that we're changing too.
