I used to hang out all night
Ladies on the left and and the right
They used to call me mr. Shady down low undercover
(This must be)
I didn't give a damn what I said
As long as they awoke in my bed
I was gonna get it one way or the other
(This must be)

I was just as fast as I could be
Didn't want nobody changing me
I'd go running from lover to lover
Then you walked in my life right on time
Not a penny short of a dime
And baby I'm beginning to discover

This must be love
It must be love, yeah
Cause tell me what is love
If this ain't love
This must be love
It's gotta be love, yeah
Cause tell me what is love
If this ain't love

It's all because of you
I'm doing all the things I would not do
I've come so far I don't think I'll recover
Now everybody in the world can see
That you've become the biggest part of me
And I could never leave you for another

This must be love
It must be love, yeah
Cause tell me what is love
If this ain't love
This must be love
It's gotta be love, yeah
Cause tell me what is love
If this ain't love

Oh when you come close to me
I know this is the way
That it's supposed to be
Ever since that day
You came up around my way
You're all that I think of
And I know this must be love

This must be love
It must be love, yeah
Cause tell me what is love
If this ain't love
This must be love
It's gotta be love, yeah
Cause tell me what is love
If this ain't love

You got me saying things I would not say
On top my things to do today
All I ever want to do is love ya
It's like I was blind but now I see
I can't believer the change inside of me
And baby I'm beginning to discover

This must be love
It must be love, yeah
Cause tell me what is love
If this ain't love
This must be love
It's gotta be love, yeah
Cause tell me what is love
If this ain't love
