Interestingly enough, they use one of the tracks from MM7 in the commercial (though I think they only use the vocals). It's been a while since I've played MM7 and I forget where this track was used in the game (I think it was in the undead outdoor map with the dwarf palace up on a plateau).

I've had some trouble posting direct links in the past, but if you google "qubism commercial" that will give you the right one.
