It's only 10 seconds, but the driving guitars and machine gun double bass make me want to go balistic.
Arch Enemy - "Leader of Rats"
Straight up dominating metal riff with blast beats.
Days of the New - "The Downtown"
It's a beautiful song, and makes me want to weep uncontrolably.
Hatebreed - "A Call For Blood"
Guitars hit right off the bat, and you know they'll never let up. Hatebreed's the most efficiently emotional metal band I've ever heard.
Himsa - "Kiss or Kill"
Normally, I don't like these guys, but their "technicality" in the opening is just sick.
Meshuggah - Catatonic Transfiction"
It's recorded at low pitch, then it ****ing erupts into madness. Nice 10 seconds with which you need to prepare yourself for the onslaught of "math metal's" most technically perfect band ever.
Metallica - "The Shortest Straw"
Lars and Kirk/James matching drums and guitar flawlessly then bashing it out into another old school driving Metallica track. Yummy.
Motorhead - "Ace of Spades"
Too ****ing obvious. If you don't feel like you wanna get in a barfight after this opening, you're not metal.
Oasis - "Roll With It"
It screams The Beatles, and it rolls right into a fantastic Fab Four-ish track.
Queensryche - "Silent Lucidity"
Not so much a riff, but that doesn't matter. It's the most beautiful song by a metal band ever. Has stood, and will stand the test of time forever. Cry every single time I hear it.
Rammstein - "Weisses Fleisch"
The riff after the elctro intro, picture it with fire and explosions and a huge German crushing a mic in his hand. ****ing powerful.
Shadows Fall - "Destroyer of Senses"
Old school Shadows Fall, and it's like electric sex, the opening. Groovin'.
Shadows Fall - "Eternity Is With"
They're my favorite band, so they get two. The opening here, you can feel every slash. Each one on a different chord, then an explosion of 5 with an insane thunder cymbal backing then double bass..cream.
Slayer - "War Zone"
It's Slayer, it's about war, and that's all you need to know.
Soilwork - "Observation Slave"
If Meshuggah ever needed a replacement, these guys are their technical level clones. Crushing Mesh-like riffs in the open.
U2 - "Where the Streets Have No Name"
Soft opening is like being lifted up into heaven by God himself.
lul infront of the storm kicks in, you know whats coming, you get all excited and then nearly snap your spine headbanging when it kicks in.
Fear Factory - Edgecrusher
when a song has a disclaimer at the start, you know its gonna stomp on your ass. and it does. for 4 minutes.
Stuck Mojo - Give War a Chance (or, for that matter, anything off Declaration Of a Head Hunter)
slammin. straight up, ball tearin, ass kickin, mother f*ckin' music. love it.
there are more but i've got a bad memory for names. damn that pot

Too many to name, first ones that spring to mind are Moonlapse Vertigo, The Moor and Bleak by Opeth; Master of Puppets (several) and Battery by Metallica; more or less any of Tom Morello's; BYOB by SOAD.
