歌名:Gangsta's Paradise

歌词:As I walk through the valley of the shadow of death
I take a look at my life and realize nothing's left
Cause I've been blasting and laughing so long that even
My mama thinks my minds gone but I ain't never crossed
A man that didn't deserve it.
Me be treated like a punk, you know that's unheard of
You better watch how you're talking and where you're walking
Or you and your homies might lined in chalk

I really hate the trip but I gotta loc
As the croak I see myself in the pistol smoke
Fool! I'm the kinda g that little homies wanna be like
All my knees in the night
Saying prayers in the street light..

( chorus )
Been spending most of our lives living in the gangsta's paradise (x2)
Keep spending most of our lives living in the gangsta's paradise (x2)

Look at the situation, they got me facing
