strThat = '''Sarah Connor-that girl
(That girl!)Ow~yeah! Um!Are you talk about me?
(Um!Yes,I can trust.)
Red carpet rolling, pockets are swollen
Still got my friends, and with them I be flowing
Rocking don't stopping and shopping
Still coming on strong, I'll be flossy!
This one's just for you
I'm taking it to level,too.
Tell me why you're talking trash
They talk about that girl on the scene,
Fusing that gucci on TV.(ah ha)
That girl with the car
20 inch rims on the jaguar.(ah ha)
That girl on the show
Thinking that bird just like a cock.(ah ha)
That girl, that girl
(That...taht...that...taht...that...)
I take things step by step
Until there's nothing left
But the top and it don't stop
When I sign off, I can hear the beat drop
No matter what I do, I can't do right by you
You can chat chat the chadder but it don't matter
This is for you
(Ha!Ha!Ha!...)
They talk about that girl on the scene,
Fusing that gucci on TV.(ah ha)

20 inch rims on the jaguar.(ah ha)

Thinking that bird just like a cock.(ah ha)
That girl, that girl
(That...taht...that...taht...that...)
(That girl on the scene,fusing that gucci on TV.(ah ha)
(That girl with the car,20 inch rims on the jaguar)(ah ha)
(That girl on the scene,fusing that gucci on TV.(ah ha)
(That...taht...that...taht...that...)
I will be shining, you'll be crying
You don't wanna front with me
On Vina and on MTV
I'm gonna still be me
And I will be shining you'll be dying
You don't wanna front with me
Toe to toe on MTV
I'm gonna still be me
