Is the music game genre oversaturated? Some might say yes. I'd argue otherwise; there's still plenty of good music out there that isn't available in video game form. In any event, we have some details about Harmonix's upcoming cutesified LEGO Rock Band. Iggy Pop will be appearing in the game, as the tutorial voice, and also in plastic action figure form, as you an see above. Iggy's song "The Passenger" will be in the game's song list.
