This is a song about "Doing time"

I can feel your heart beating fast

Aint doing time for a shank

Aint doing time for a plant

Just hustling you understand

Cause i'm doing great, by myself,

Wish i could shed all these tears

Get off a key like i can’t sing

C'mon son, the fuck you think you doing

Doing every day things, at night

So my cup is full, too much pain to fight

Half of the time i dont even know what im doing

Fuck the fat lady, it's over when all the kids sing

Pick your poison tell me what you doing

She floating round winners, now your bitch you losing

He's the one doing his stuff

Thought this was forever love
