"When I Need You"的詞曲作者是Savan Kotecha。以下是歌曲的歌詞：
(Verse 1)
'Cause I need you like the sunshine
Burning brighter than the brightest star
You're everything I need and more
In the morning and the hour of my need
(Chorus)
When I need you, need you like the rain in June
The leaves on a new-born tree, new life I'm loosed and free
And you are here with me to set my spirit free
So I know there's no limit to what I can be
(Verse 2)
No sleepless night when I'm alone
Without you, I'm lost, like a ship on the ocean alone
But you're my anchor, my guiding light
You're my comfort, my melody
(Chorus)
When I need you, need you like the rain in June
The leaves on a new-born tree, new life I'm loosed and free
And you are here with me to set my spirit free
So I know there's no limit to what I can be
(Bridge)
I'm not afraid of anything that might come my way
Because I know that you will always be there for me
And that's what makes me feel safe and free
(Chorus)
When I need you, need you like the rain in June
The leaves on a new-born tree, new life I'm loosed and free
And you are here with me to set my spirit free
So I know there's no limit to what I can be
(Outro)
And I know, there's no need to doubt
When you have someone like me who needs you just as much.
