If you think some of the music download prices can be somewhat of a stretch (like I do) well then your in luck. Activision and Coca Cola are doing a promotion of the latest DLC offerings of DJ Hero 2 and Guitar Hero: Warriors of Rock for the low price of free! DJ Hero 2's DLC is DJ Tiesto-mixed three-track pack and Warriors of Rock will be My Chemical Romance pack, each of which is free via redemption code while supplies last.
