Master of the puppets
For whom the bell tolls
harvester of sorrow
four horsemen
whiskey in the jar
and justice for all

King of nothing

well their best song is MASTER OF PUPPETS!!
and enter sandman would be #1 if not for its terrible lyrics. i mean, even when i accept that its a song about em.. little kids scared of the dark; i still cant take how goddawful the writing is. those morons. so ENTER SANDMAN is #2, for having the best post-sabbath riff ever.
ONE is a cool acoustic bit, i think it rules. #3
and everything else on master of puppets is #4-whatever

<----------- Anything off that. and everything else.

You think the lyrics to Enter Sandman are bad? Well they are but have you heard the lyrics to their latest album... "flush it out"
ha ugh it is terrible...

lyrics are to metallica as guitar riffs are to linkin park

or as living is to princess diana

about time someone got her again

Best Metallica songs in my opinion are as follows:

Fade to Black
One
Welcome Home (Sanitarium)
Master of Puppets
Damage Inc.
Battery
Ride the Lightning
For Whom the Bell Tolls
The Four Horsemen
Seek and Destroy
Call of Ktulu
Creeping Death
Whiplash
Fight Fire With Fire

maybe...

Blackend
Harvester of Sorrows
Eye of the Beholder

if you really want to be generous...

Enter Sandman
Unforgiven
Sad But True
Don't Tread on Me

worst possible songs i've heard

Most of Load and ReLoad.
All of S&M
Saint Anger (I deplore that song and never heard the entire album and never will. Would rip my ears off first.)

I think S&M kicks ass.

The best Metallica songs would have to be:

Hit The Lights
The Four Horsemen
Seek and Destroy
Whiplash
Phantom Lord
Ride the lightning
Fight Fire with Fire
Creeping Death
Battery
Master of Puppets
Leper Messiah
One


The rest are just for filler and commercial purposes

or maybe i just didnt feel like typing them all, how about that
