The song That Was Then is performed by Jesse McCartney .
Guess you never really know just what you've got
'Til you finally realize she could be gone
And know that I've been taking you for granted
For the longest time
All you want is someone who really cares
And I didn't even notice you were there
I promise that I'll never ever
Make that same mistake not twice
That was then, this is now
Take some time to come around
All I wanna do
Is try again, show you how
I know that it's all about
Givin' attention to you
I was a fool for way too long
What you wanted I could not see
That was then, this is now
Took some time to figure out
Love is all you need, yeah
Guess I never thought about it before
I was thinkin' of myself and nothing more
Didn't even wanna try to find out
How you really feel
Now I see that I'm the lucky one it's true what we got
You know I never want to lose
I was trippin' in a fantasy
And missing what was real
That was then, this is now
Take some time to come around
All I wanna do
Is try again, show you how
I know that it's all about
Givin' attention to you
I was a fool for way too long
What you wanted I could not see
That was then, this is now
Took some time to figure out
Love is all you need
I used to be someone
Who only really thought about themselves
And no one else and you could tell baby
But as before I understood, be with you
'Cause something is good
Gotta let her know and I want you to know
You're always my priority
And I wanna give you more
Than all the love you need
Took a little time
Now you know my fantasy
That you're my world, yeah
I never want our love to fail, [Incomprehensible]
I'm gonna do whatever it takes
No I'm never gonna let it slip away
'Cause you're my girl, yes you are
That was then, this is now
Take some time to come around
All I wanna do
Is try again, show you how
I know that it's all about
Givin' attention to you
I was a fool for way too long
What you wanted I could not see
That was then, this is now
Took some time to figure out
Love is all you need
You're always my priority
And I wanna give you more
Than all the love you need
Took a little time
Now you know my fantasy
That you're my world
I never want our love to fail, [Incomprehensible]
I'm gonna do whatever it takes
No I'm never gonna let it slip away
'Cause you're my girl, yes you are
That was then, this is now
Take some time to come around
All I wanna do
Is try again, show you how
I know that it's all about
Givin' attention to you
I was a fool for way too long
What you wanted I could not see
That was then, this is now
Took some time to figure out
Love is all you need
Comin' around
And ready to show you how
I'm gonna change girl, baby
