Solved: can't find title for metallica song

ok the begining of the song is a siren then a guitar comes in. im almost posistive its by metallica i just don't know the title of it. i can include more details if needed (like more lyrics) but i think it should be fairly easy to figure out what it is.

lyrics from some part of the song:

should of seen the signs, then i heard the siren, oh no, oh no

(comas are pauses in the singing)
please help!

The Unforgiven I and II start with what is supposedly a siren but the lyrics don't seem to be the same as those you've said.

May be worth a listen:
Unforgiven I
Unforgiven II

yea i already know and like all the unforgiven songs so thats not it

and the siren at the begining sounds more like a cop car and then it goes right into heavy rock or metal

never mind i figured it out it was by adifferent band

what was the name of the song as i think i might be searching for the same one that you were?

the name of the song trune out to be:

Imminent Destruction
by: Eternal Decision

if u look on itunes you should be able to find it (it's not that popular a song) if u dont have itunes u could try youtube or download itunes for free
