《One Direction One Thing》的歌詞如下：
Girl you know you got it right
You're so beautiful and sweet
That's what makes me love you more night to night
I know that we've only just met
But I'm so sure about it
That I want to make it last forever
One thing for sure
I'm gonna love you till the end
And I'm never gonna let you down
You're my one thing
You're all I need girl you know it
You light up up up when you smile
And it's no wonder that I'm in the clouds up up up up up
When I look at you I just can't deny it
It's no doubt in my mind that you're the one for me girl you know it
I know that we've only just met
But I'm so sure about it
That I want to make it last forever
One thing for sure
I'm gonna love you till the end
And I'm never gonna let you down
You're my one thing
One day when we're old and gray
