He released this song for US, his fans. He went to the label and said “I want my fans to hear this song before the album comes out, even if it’s not a single.” And he did it a couple of times (according to his tweets).
It’s his favorite song on the album and “sums him up.”
And it’s all about how how human he is, how much he hates the headlines and how most people only get half the story.
He wanted people to hear that NOW, not later whenever his album comes out. Right now.
I think that, in and of itself, means something, too.
