The song The Certainty is performed by Posies .
Here's how to understand your friends
It's been like six years of the same thing
Nothing can be believed unless you say it
Nothing but good times up ahead for you
Here's how to occupy your mind
Take some skills and learn to build a reason
Nothing can be perceived 'til you betray it
Nothing but fine times up ahead for you
And if we build a car that drives on empty eyes
And call it "laughing matter"
Nothing matters
It's all up for you
