Probably the reason it's a little hard to break away from the album format completely is, if you're getting a band together in the studio, it makes financial sense to do more than one song at a time. And it makes more sense, if you're going to all the effort of performing and doing whatever else, if there's a kind of bundle.

By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.
