360 owners got a free Halo song, it's only fair PS3 owners get a similar deal. And they are. An email just went out to PlayStation Underground members, announcing that on June 5, a "Free GoW song for Guitar Hero III" would be released. Surely this signals the beginning of a "free, exclusive track" arms race, which can only end when players are subjected to weekly updates like "The End Credits Music From Heavenly Sword" and "Bomberman Zero Main Menu: Ibiza Party Megamix".
