All you need is love? Yeah, I don’t think so.

Added to the growing Guitar Hero Music Store today were three metal-themed offerings from huge names in the thrash business, Dethklok, Amon Amarth and Shadows Fall.

Think the Guitar Hero name was soiled by last year’s teenager-oriented Band Hero?

I urge you to think again. Embedded below are the songs added to the Music Store today. Each is $2 and I’ll be snagging all three. You with me?

Dethklok- Laser Canon Death Sentence

Amon Amarth- Twilight Of The Thunder God

Shadows Fall- Still I Rise

Sure, I’m pushing my metal agenda, but the guitar and drum work, not to mention the vocals, should be challenging and fun in Guitar Hero.

Harmonix today announced that selections from Green Day’s “21st Century Breakdown” album, and tunes from bands playing this year’s MayhemFestival nationwide tour are next week’s batch of Rock Band DLC.

It’s hard to believe that Green Day has yet to grace a music game, but next week, when “21 Guns,” “East Jesus Nowhere,” and the radio-friendly “Know Your Enemy,” we’ll finally be able to rock out to tracks from the popular 90′s band.

On the death metal side of things, Harmonix is dropping 8 tunes from bands playing this summer’s Mayhem Festival (I’ll be at the August 8 show!) and fans of this particualr flavor of music can finally, finally, rejoice.

Behemoth “Conquer All”
Black Dahlia Murder “What a Horrible Night to Have a Curse”
Cannibal Corpse “Hammer Smashed Face”
God Forbid “Empire of the Gun”
Job for a Cowboy “Embedded”
Marilyn Manson “Disposable Teens”
Slayer “Black Magic”
Whitechapel “This Is Exile”

I’m very much excited about the metal inclusion, and am truly hoping for a all-out metal smackdown of a game from either Guitar Hero or Rock Band. Call it Guitar Hero Thrash? Sounds good to me.
