Many have tried, all have failed, but in the end it only took four animated children from Colorado to topple Kanye West’s ego.

Get ready to sing like Axl and emulate whichever guitarist is in Guns n’ Roses these days: Gn’R debuted their song “Shackler’s Revenge” on Rock Band 2, and now Axl Rose will bring the rest of Chinese Democracy to the music video game on April 14th as a new batch of downloadable content. Thirteen tracks off Chinese Democracy — Rock Band is assuming you’ve already beat enough challenges to add “Shackler’s Revenge” to the in-game track list — will be available both in bulk and as individual tracks for Playstation 3 and XBox 360, while the Wii will only sell CD as individual tracks.
