DJ Hero 2, Guitar Hero: Warriors of Rock demos shred onto Xbox Live

It’s a daily double download Tuesday!

Activision has released samplers for its two music games today exclusively onto Xbox Live. Four-song trials for DJ Hero 2 and Guitar Hero: Warriors of Rock are now primed and ready for you to download.

Mixes included in the  DJ Hero 2 demo are: Pussycat Dolls Featuring Busta Rhymes “Don’t Cha” Mixed With Pitbull ”I Know You Want Me (Calle Ocho),” Lady Gaga Featuring Colby O’Donis “Just Dance” Mixed With Deadmau5 “Ghosts N Stuff,” MSTRKRFT Featuring N.O.R.E. “Bounce” (Battle Mix), and Estelle Featuring Kanye West “American Boy” Mixed With Chic “Good Times.”

As for Warriors of Rock, those who download the demo for the plastic instrument band game will get a first look at the game’s Quest Mode (narrated by KISS frontman Gene Simmons), and can jam out to the following tunes: Black Sabbath “Children of the Grave,” Foo Fighters “No Way Back,” Slash featuring Ian Astbury “Ghosts,” and Dethklok “Bloodlines.”

It is unclear if the two demos will also come to PlayStation 3 owners via the PlayStation Store. Here’s to hoping, Sony faithful!
