《Lost in Love》的詞曲由甲殼蟲樂隊（The Beatles）的約翰·列儂（John Lennon）和保羅·麥卡特尼（Paul McCartney）共同創作。以下是該歌曲的部分歌詞：
I'm lost in love
It's got me feeling like a fool
But I can't stop
Because I love you so
You were made for me
Like a diamond in the night
And I was made for you
To dance across the light
Chorus:
Lost in love
It's a beautiful game
I'm lost in love
With you, yeah
You're all I need
And all I ever wanted
And I don't know what to do
Because I'm lost in love with you
Bridge:
Oh, it's a lonely feeling
To be up here on your own
But I don't care, baby
I'm lost, I'm lost, I'm lost in love with you
Chorus:
Lost in love
It's a beautiful game
I'm lost in love
With you, yeah
It might be wrong
It might be right
But when we touch, darling
I lose my mind tonight
I lose my mind tonight
I lose my mind tonight...
Lost in love with you...
Lost in love with you...
