Billionaire.

Billionaire: This song is about someone who wants to achieve a dream. Coincidentally, the same thing happens to us all: Always dream of reaching the highest in the world, we want to be big and have lots of money. But if we analyze the previous song "Price Tag" we can be, but always maintaining our humility and never make it a priority to the ambition and money. For the same reason that the saying  "Money can not buy happiness" So, here's the song too... Enjoy it. (:
