Your favorite Metallica Song is...

Blackened. I've seen them live a number of times and sadly I've only heard it live once.

honestly, probably Battery. I'm not a huge metallica fan but I enjoy the old thrash stuff

The Frayed Ends Of Sanity

Also Bleeding Me from Load (which is a fucking awesome album)

Fade to Black for me.

The Thing That Should Not Be.

My username might be a hint there.

Either King Nothing or The Unforgiven II

Load and reloaded are awesome

I mean as corny as it is as a choice, it's Fade to Black

Enter Sandman.

That's all I can think of.

Battery.

Escape, Trapped Under Ice or Leper messiah. I am partial to No Leaf Clover as well

the one with the zombie apocalypse animated music video

that one was kind of cool

Master of Puppets

For Whom The Bell Tolls.

The flow of that song is just perfection.

Out of the gates with Load and Reload as best albums? Wow.

I kinda like Load actually

Their cover of Blitzkrieg

Battery..

Probably the S&M version of One.

I like Outlaw Torn, but I think my oddball Load/Reload era pick would be Low Man's Lyric.

St. Anger

Battery or Creeping Death

Learning to play the song, Ride The Lightning, on guitar really made me appreciate and love it even more. Lot of fun and tough rhythm guitar work on that song. Master of Puppets is also a crazy exercise in both fretting and down strumming for your hands.

Orion

I have a soft spot for Jump In The Fire.

One and Unforgiven II

For Whom The Bell Tolls is up there too...

Fade to Black. It has a little bit of everything I like about Metallica and music in general.

Harvester of Sorrow gets me so pumped. OP had a great choice as well.

Fade to Black

This is a tough one. I guess I would choose Harvester of Sorrow.

Hero of the Day

I couldn't name just one, but for some reason No Leaf Clover jumps out at me by virtue of only being on S&M.

Maybe ...And Justice for All?

I kind of want to say Four Horsemen but then I remembered that I only like that song because of its similarities to Mechanix and that I don't actually like it on its own.
Orion is really high up there for me. Any of the S&M versions of any of their songs are as well; I listened to that CD so much in 7th grade.
I think I'll go with Nothing Else Matters maybe as my favorite.

EDIT: Nope, just listened to No Leaf Clover for the first time in years and that's my choice.

Battery

Glad to see Load and Reload getting some love. I have to go with Bleeding Me, but could be one of several depending on day of the week (Fade to Black, And Justice for All, My Friend of Misery, Fixxxer, Low Man's Lyric, All Nightmare Long, Atlas Rise, Spit Out the Bone) .

No Leaf Clover.

No Remorse!

One.

I mean, how can it not be. The build-up and climax are legendary.

It's gotta be Enter Sandman. Thank god for the years of exposure to it ECW gave me.

Master!

Master!

Master of Puppets I'm pulling your stringsssssss!

Phantom Lord.

And Justice For All.

One or Master of Puppets.

Wherever I May Roam. That riff gets me everytime.

Four Horsemen.

Of the 90s era, always was fond of the unforgiven II.

The Four Horsemen

I have a confession.

I still can't listen to the title track on RTL. It scares the shit out of me.

For Whom the Bell Tolls or Creeping Death. (Justice is the best album though.)

One. Favorite song, period.
