Down low undercover
'Cause tell me what is love
I can't believe the change inside of me
This must be love
You're all that I think of
It's gotta be love, yeah
All I ever want to do is love you
If this ain't love
If this ain't love
This must be love
I know this is the way
'Cause tell me what is love
This must be love
I was just as fast as I could be
It's like I was blind but now I see
This must be love
If this ain't love
You came up around my way
As long as they awoke in my bed
'Cause tell me what is love
They used to call me Mr. Shady
It's gotta be love, yeah
Oh, when you come close to me
It's gotta be love, yeah
I was gonna get it one way or the other
I didn't care what I said
This must be love
And I know this must be love
'Cause tell me what is love
If this ain't love
It's gotta be love, yeah
Ever since that day
Now everybody in the world can see
That you've become the biggest part of me
On top my things to do today
This must be love
'Cause tell me what is love, if this ain't
It must be love
Didn't want nobody changing me
And baby, I'm beginning to discover
That it's supposed to be, yeah
This must be love
This must be love
It must be love, yeah
This must be love
It must be love
Tell me what is love, if this ain't love
This must be love
It's all because of you
You walked into my life right on time
It must be love, yeah
If this ain't love
Not a penny short of a dime
I've come so far I don't think I'll recover
You got me saying things I would not say
Tell me what is love, if this ain't
'Cause tell me what is love
'Cause tell me what is love
'Cause tell me what is love
If this ain't love
'Cause tell me what is love
'Cause tell me what is love, if this ain't
I'd go running from lover to lover
It's gotta be love, yeah
But baby, I'm beginning to discover
If this ain't love
If this ain't love
It must be love, yeah
And I could never leave you for another
I'm doing all the things I would not do
