Rock out to WoW, free GHIII DLC now available

Yesterday, we told you about World of Warcraft's "I am Murloc" track making its way to Guitar Hero III as downloadable content. Well, we just wanted to inform you that today the 14MB track became available for download off the XBLM and can be downloaded for FREE! Free WoW themed Guitar Hero DLC, what could be better? What's that? Free WoW themed Rock Band DLC you say? Come on now, be fair and don't be that guy. For shame.
