Kurt Cobain: The Legacy

I just saw the commercial for the portable version of Guitar Hero, where some kid is playing Guitar Hero on his DS while the background transforms into scenes out of the video for "Tonight, Tonight" (note that anything involving space backgrounds and music makes me think of the "Tonight, Tonight" video) and "On a Plain" plays in the background. Somehow, I feel like every time that ad comes on, Kurt Cobain goes into a high speed spin cycle in his grave. You know, because he hated the commercialism so much. I bet Courtney justifies it to herself, though. Preserving the legacy and all that.
