WILL.I.AM'S new song "that power will i am ft justin bieber"

I think that this song is about, how he grew up,and his brother's was looking after his mum .
He used to have a piggy bank, but now he's got a bigger bank. I think he said that because he has a lot of money...So he donated 100,000 dollars to us. He say's who cares about the haters say. They hate on him because they can't do what he does.
He say's they he hates to bust your bubble. he takes it higher, in his singing.
