[Verse 1]
What is this look I often see
Faces filled with ecstasy
What's going 'round
Tell me, what have they found
I've been searchin' for the answer
Trying to work my feelings out
I been up all night, girl
Nothing is going right

[Pre-Chorus]
Since we met, I've had some problems
With words I couldn't say
Now you've changed my life forever

[Chorus]
This must be love
The one I heard about
No other kind of feeling
Turns me inside out
Yes, this must be love
Controlling my heart and mind
Let's take a vow to make it last
'Til the end of time
'Til the end of time
[Verse 2]
It's a strange sensation, a new creation
And I just don't have a defense against it
I'm completely outdone
For the first time there's only one
The things I did, I don't do no more
There's no desire, no looking for
Who or what is to blame
No, it cannot be explained

[Pre-Chorus]
Since we've met, I've had some problems
With words I couldn't say
Now you've changed my life forever

[Chorus]
This must be love
The one I heard about
No other kind of feeling
Turns me inside out
Yes, this must be love
Controlling my heart and mind
Let's take a vow to make it last
'Til the end of time
'Til the end of time
[Instrumental Break]

[Bridge]
Something's come over me
You're all my eyes can see
Whatever it may be

[Chorus Outro]
This must be love (Must be love)
The one I heard about
No other kind of feeling
Turns me inside out (Turns me inside out)
Yes, this must be love
Controlling my heart and mind
Let's take a vow to make it last
'Til the end of time ('Til the end of time)
'Til the end of time
