《Goodbye Happiness》的歌詞如下：
I don't know where I belong
But I'm tired of feeling small
In this game of life I play
Trying to fit in this big game
But now I'm gonna let it go
Goodbye Happiness
Gonna let it all go
Goodbye Happiness
I've been searching for a sign
Trying to find a way to be
In this world that's not my own
Trying to find my way home
But now I'm gonna let it all go
Goodbye Happiness
Gonna let it all go
Goodbye Happiness
And now I'm flying high above
Through the clouds without a trace
I'm free at last to be me
And I'm not gonna lose that chance
So here I am, standing tall
Goodbye Happiness
Gonna let it all go
Goodbye Happiness
Everybody hurts sometimes
But now I know that I can fly
And I won't let anyone bring me down
Not anymore, no, no, no
Gonna let it all go
Goodbye Happiness (x2)
Gonna let it go, gonna let it go (x2)
Goodbye Happiness (x2)
