Fun but stagnant music game has songs with iffy lyrics.

Summary: Parents need to know that Green Day: Rock Band garnered a "Teen" rating by the ESRB because of some lyrical references to drugs and sex, some unlockable videos where a bandmenber makes a joke about cocaine, and "mild blood" seen in a photo you can unlock that shows the band reenacting a bloody crime scene. The game does encourages players to express their passion for music and cooperate with friends.
