《heads or tails》的詞曲作者是艾薇兒·拉維尼。以下是《heads or tails》的歌詞：
If I ask you where you are
Are you with her or with me tonight
You never give me straight answers
So now I'm asking again
Will it be heads or tails
Will it be good or bad
Am I gonna love or be alone again
Will it break my heart or make me laugh
Am I dreaming too much or too little
And I need to know
You could tell me there's no chance
And I'd say alright, I'll move on
But when you tell me we're back
I'm paralyzed again, I can't believe my ears
Will it be heads or tails
Will it be love at first sight again
Will it be safe in your arms
Or will we crash and burn again
Will it hurt more than the last time
Are we better off alone?
Cause all I want is for you to tell me the truth
Is there any point in hoping anymore?
Oh my heart says go for it again
Oh my mind says stop playing games
But my heart keeps saying go for it again
And I need to know, oh I need to know
Will it be heads or tails? (x2)
Will it be love or just a phase? (x2)
Am I gonna fall or am I gonna fly? (x2)
Oh I need to know, oh I need to know now! (x2)
