以下是《Betcha》的部分歌詞：
女：
Betcha can't forget about me
男：
Betcha can't get over me
女：
Betcha know no matter what you do
男：
You'll always miss me like you ought to
女：
I'm the reason why you sweat
男：
I'm the flame that keeps you alive
女：
I'm the flame that burns in your heart
男：
And I'm the fire that you can't douse
女：
Betcha can't forget about me
男：
Betcha know you can't forget me now
女：
So why try to fight it, it won't go away
男：
You can try to deny it but you can't stay away from me tonight
女：
I'm the reason why you breathe
男：
I'm the flame that keeps you hot and fresh
男女合唱：
You got to believe, I can take it to the top
No looking back, just running out of room
Gonna break you down, but build you back up again, oh yeah.
Betcha can't forget about me (you can't forget)
Betcha know no matter what you do (you can't get over me)
So why try to fight it, it won't go away (no no)
You can try to deny it, but you can't stay away from me tonight.
