The rozzers are after me.

Is it a request at some kind of Bab Marley karaoke?

Big City Life,
Me try fi get by,
(I have to fight/struggle to survive/get by)
Pressure nah ease up no matter how hard me try.
(The pressure never eases no matter how hard I try)
Big City Life,
Here my heart have no base,
(I don't belong here)
And right now Babylon de pon me case.
(And right now, the authorities they're on my case/ they've singled me out)

'Babylon', refers to more than just the Police, but the System of Authority in general and it's agencies, particularly those viewed as oppressive.
