This is a song about "By"

I shine like something in the sky

I'm just living trying to get by

Sweet, okay makes sense

I'm a mob by myself/

Just me trying to skate by

Live off my lie and my lullaby

So drop the slam and let's get sick

Brush by the bleak brick by brick

By the altered consciousness caused by drug over dosage.

When he see the jugs he will wanna rush to get a quick touch

Spread by mosquitoes perhaps spread by a needle

Forever i ain't run yet and i never will

Had to teach the bitch manners, now i gotta learn her

Musician by heart , instrumentalist by nature
