Bodom!!!! <3
Hmmm get sum Pantera, Iron Maiden, Anthrax, Slayer

Children of Bodom are pretty much heavy metal/power metal, although many people and sites (including wikipedia) will lead you to believe that they're melodic death metal. Honestly the only thing death metally about them are the vocals- but that can also be said for a few other "melodic death metal" bands.

Depends on what your tastes are. It's probably best to start off with classics like these:

Heavy Metal/NWOBHM
Iron Maiden - Number of the Beast, Powerslave
Judas Priest - Sad Wings of Destiny, Screaming for Vengeance
Manowar - Hail to England, Battle Hymns
Black Sabbath - Black Sabbath, Paranoid
Dio - Holy Diver

Power Metal
Lost Horizon - A Flame to the Ground Beneath, Awakening the World
Blind Guardian - Nightfall in Middle Earth, Imaginations from the Other Side
Helloween - Keeper of the Seven Keys pt 1 & 2
Kiuas - The Spirit of Ukko, Lustdriven
Kamelot - The Black Halo, Epica
Sonata Arctica - Ecliptica, Reckoning Night
Evergrey - The Inner Circle, Recreation Day
Firewind - Allegiance, Forged by Fire
Iced Earth - Something Wicked This Way Comes
Ensiferum - Ensiferum, From Afar (these guys are folk metal, but I decided to put them here so I didn't create another list with just two bands on it).

Progressive Metal (note: some of the following bands may be a fusion of 2 or many more genres, or, in the case of early Queensryche/Crimson Glory, not prog at all)
Queensryche - Empire, Operation Mindcrime, The Warning
Symphony X - The Divine Wings of Tragedy, V: The Mythology Suite, Paradise Lost, Twilight in Olympus etc...
Pain of Salvation - Remedy Lane, The Perfect Element, Entropia, One Hour by the Concrete Lake
Dream Theater - Images and Words, Scenes from a Memory
Crimson Glory - Transcendence, Crimson Glory
Ayreon - 01011001, The Universal Migrator parts 1&2
Devin Townsend - Terria, Addicted
Opeth - Blackwater Park, Deliverance, Damnation
Tool - Lateralus, Aenima
Shadow Gallery - Tyranny, Room V

Alternative Metal
Tool - Lateralus, Aenima (also mentioned under prog)
Faith No More - The Real Thing, Angel Dust
System of a Down - Toxicity, Mesmerize/Hypnotize

Thrash Metal
Slayer - Reign in Blood, Seasons in the Abyss
Metallica - Master of Puppets, Ride the Lightning
Megadeth - Rust in Peace, Peace sells... but who's buying?
Pantera - Cowboys from Hell, Far Beyond Driven (though FBD isn't thrash but groove metal)
Anthrax - Among the Living, We've come for you all
Testament - Practice what you Preach, The Legacy
Sepultura - Beneath the Remains

Melodic Death Metal
In Flames - The Jester Race, Whoracle
At the Gates - The Red Sky is Ours, Slaughter of the Soul
Dark Tranquility - The Gallery, Damage Done
Amorphis - Tales from the Thousand Lakes, The Karelian Isthmus
Amon Amarth - With Oden on our Side, Versus the World
Skyfire - Timeless Departure, Spectral

A few of these are considered to be the greatest metal albums ever (Number of the Beast, Master of Puppets etc), and a few are just personal recommendations. I (or many others) could select 50 greater albums, but I don't think that's necessary.
Better get listening!

APC are good, I haven't heard a great deal of them but I know that they are good and more Maynard-driven than Tool are.

I'd probably start with one or two from each genre, then decide from there what genre you're most interested in, and check out the other albums of that genre.
