She's On It by Beastie Boys

There's no confusion in her conclusion
She wants to waste my time and that's no delusion
Her final decision is perfection and precision
She's grade A class - number one in her division

(chorus) She's on it

She acts like a nag - I don't know how it started
Even when I'm chillin' - she acts retarded
It's gets annoying - so high on the tip
If a pirate had a Def Jam shirt - she'd be hard on his tip

(repeat chorus)

Cold chillin' in the spot - and she won't stop
She'll do what's best just to reach the top
She studies real hard - all night she'll cram
In school she majors in advanced Def Jam

(repeat chorus)

Her bedroom eyes - they start to twitch
But she won't front cause she's got that itch
She'd drop to her knees if I'd only say please
Instead of counting sheep - cold counting Beasties

(repeat chorus)
