The modal verb CAN’T, bolded in the text means

DAVID GUETTA - TITANIUM

You shout it out

But I can’t hear a word you say

I’m talking loud not saying much

I’m criticized but all your bullets ricochet

You shoot me down, but I get up

I’m bulletproof nothing to lose

Fire away, fire away

Ricochet, you take your aim

Fire away, fire away

You shoot me down but I won’t fall, I am titanium

You shoot me down but I won’t fall 

I am titanium, I am titanium, I am titanium, I am titanium.
