《Just Wanna Know》的歌詞如下：
女：
You keep me waiting
In the dark and now you’re just a text away
You said you wanted to take it slow
Now I’m just asking if you feel the same
男：
Don’t know what I’m supposed to say
No I can’t promise you any thing
All I know is that I really like
The way you make me feel tonight
女：
Just wanna know if you miss me
Just wanna know if you’re thinking of me
Just wanna know if you feel it too
Are we just playing pretend or is it real
男：
I don’t want to pressure you
But I need to know what’s going on
Am I just in your bed or are we something more
Tell me what you’re feeling and I’ll let you know
女：
Just wanna know if you feel it too
Are we just playing pretend or is it real
I don’t want to lose you without getting it right
So tell me baby what are we supposed to do tonight
合唱：
Are we gonna be together
Are we just lovers in a song
I don’t want to let you slip away
I want more than just a goodnight kiss tonight
男：
If this is real to you
Let me know if it’s with you too
I don’t want to lose you in the dark again
Come and lay with me and I will show you what we are
女：
Just wanna know… yeah
男： I want to know… yeah
