Check out those lyrics: Don't look back until you've tried a line that feels so alive outside of you it's just tomorrow started. I mean WTF? But it just "sounds right". And the emotion he puts into his voice (something that rarely happens in today's pop music, especially with men) convinces my brain that I know exactly what he's singing about. (Basically, having to grow up into a world which is indifferent to you and the choices you make)
Later on it sounds like "I'm just a bus that you take"
