The Nintendo Wii exclusive, Battle of the Bands has shipped out to retailers according to THQ. The game features an innovative head-to-head battle system that uses 30 hits from several different music genres. The game will set you back $49.99 if you feel the need to set down Guitar Hero or Rock Band to pick it up. Chuck kind of dug the game at the THQ gamer`s day event a while back so it might be worth checking out.
