slave to the grind

let us read from the book of Skid Row:

You got me forced to crack my lids in two I´m still stuck inside this rubber room I gotta punch the clock that leads the blind I´m just another gear in the assembly line - oh no

The noose gets tighter around my throat But I ain´t at the end of my rope ´cause I won´t be the one left behind Can´t be king of the world If you´re slave to the grind
