Metal; a music genre that either people love or hate. Personally, I love metal. Which is why I'm asking this question. My favorite is Ride the Lightning by Metallica, and I would post the image but for some reason I can't do that on this website. Some glitches are on this site as far as my server. Oh well. Please don't post black metal images on here.

Indestructible. Cause it's got the most metal cover ever. Dude on fire covered in chains.

Hmm... I dunno about "of all time" but Death's Symbolic and The Sound of Perseverance are two on the top of my list.
 

i cant fucking pick. 
 
speaking of metal, i hate how to me its about feeling while to others its another form of party music while to another group its so much about life and religion, etc....  im not sure what my point is.

Hard to pick a favourite but my top picks are...
Megadeth-Peace Sells But Who's Buying
Tool-Aenima/Lateralus
Mastodon-Crack the Skye

"speaking of metal, i hate how to me its about feeling while to others its another form of party music while to another group its so much about life and religion, etc....  im not sure what my point is. "

...And Justice for All.

Well you asked for the best metal album in the title. I will give you some important metal albums. 
 
 

Since I haven't listened to every metal album made I can't make an informed decision, but the best metal album I have heard is this,

Megadeth - Peace Sells but who's buying 
Queensryche - Operation Mindcrime

That some people take it far too seriously? "

Terrifyer by Pig Destroyer. 

I think all of you mean...

Black Sabbath - Paranoid.
 
It bugs me to know that some peeps say they don't consider it metal cause it's too slow. >=/

" Black Sabbath - Paranoid.  It bugs me to know that some peeps say they don't consider it metal cause it's too slow. >=/ "

Ride The Lightning is probably mine, too. 
 
Screaming for Vengeance is up there as well as the other 4 prime Metallica albums. Also 10,000 Days, The Number of the Beast and Black Sabbath's self-titled album and Paranoid.

Some great choices in here. Gonna have to go with Lateralus by Tool.

Arise by Sepultura

@PowerSerj: Oh, you're too kind, and oh look, you had to put Mayhem, the band I was thinking of when I said NO BLACK METAL.

@SJSchmidt93: Yeah, there are several reasons that I like this album, but my main one is from the i tunes exclusive, where you can hear Newsted mess up Creeping Death live with death metal vocals for thrash; no wonder he's viewed as Metallica's low point.

"Terrifyer by Pig Destroyer.  "

" @PowerSerj: Oh, you're too kind, and oh look, you had to put Mayhem, the band I was thinking of when I said NO BLACK METAL. "

@Black_Raven: Ok, but Mayhem IS Satanic. I mean, consider their history. There are some others, but I just don't want my thread full of that crap. You may call me a pussy and all, but that's how I feel about black metal.

Iron maiden-killers

The Black Parade.

Paranoid.

@GunnBjorn: Hell yeah!

@BlastProcessing: Is it just me, or is Mastodon obsessed with Moby Dick?

Don't know if this is classified as Metal.
 

@CornontheCobbe: Yeah, Fear Factory is metal.

This album contains the most metal riff ever.
 
 I AM IRON MAAAAAAAAAN!!!  DAH DAH DAH DADA! DA DA DA DA DA DA DAH DAH DA DA!! 

A lot of people know what good metal is, such as Paranoid and various Metallica albums.

@BlastProcessing: I was going to say something about Blood and Thunder but that's already on that album; you're right, they're not.

All that remains Fall of Ideals 

A lot of great albums have already been covered. So I'll give it to....
