The tragic loss of Kurt Cobain was a huge blow to many fans, but the music lived on in the fans and on the bazillion album releases after the event, probably more than 2Pac after his death. Today, Activision announced the addition of Kurt Cobain as a playable character in Guitar Hero 5. The two playable recordings are "Smells Like Teen Spirit" and a previously unreleased live version of "Lithium." Both songs are huge favorites and with Cobain being a playable character, Activision scores well with this announcement. Growing up with Nirvana and loving their music, this is a huge boon to me and will be a factor in my purchase decision.
