In this episode Pascual takes the helm and brings us some audio goodies to puzzle over. Several lawsuits have resulted over pop songs that are too similar to each other, and while some are cut and dry, others tread into that weird, philosophical territory of "what is originality, anyway?" Are we all a necessary, determinate product of our creative influences? Are notes but simple ingredients that can only be combined a certain number of ways, so we should expect recurrent themes in music on a cyclical basis? We go from pop music to the much, much older operas and even Gregorian chants, to look at the "universality" of particular note combinations that are recycled endlessly without most listeners ever knowing it. Plus, alien music!
