Earlier this summer, a trio of teenage rockers took the internet by storm with their unique blend of J-Pop effervescence and head-banging thrash metal beats. The band's star continues to rise with both a world tour and the announcement that their first hit, "Gimme Chocolate" is coming to Rock Band 4. The song will available as a bonus track beginning October 6th (which is when the game actually hits store shelves). Unfortunately, the track is exclusive to the Xbox One platform and needs to be reserved as part of the game's pre-order bundle.
