《Knees》的詞曲作者是IU，以下是這首歌的詞曲：
(Verse 1)
Oh my knees, knees, knees
Yeah, knees knees knees
Chorus)
But I don't care, I don't care
Even if I fall, I fall for you
Verse 2)
My knees are shaking, but I'm standing tall
Even if my heart's about to explode
I'm feeling something I can't explain
Chorus)
I don't care if it's a dream or reality
If it's real, I'm falling for you, for you
Bridge)
You don't even know me, and yet
I feel like I've known you forever
Like a dream or a drug that I can't get over
Chorus)
And even if my heart hurts and my head aches
I'll never give up on you, you
