After EA decided to cross-promote Portal in Rock Band via Still Alive, it was only a matter of time before the mega-merger of Activision and Blizzard would bring a World of Warcraft song into the world of Guitar Hero.

Generic guitar churns, gargling, a boring note-chart--whereas Still Alive wasn't all that great, I Am Murloc pushes the envelope on shoddy downloadable content. But hey, at least it's free.
