With a lot of modern tunes packing this week's setlist, Josh and Emily turn their thoughts to musical composition and earfeel. Where exactly is the line between a tune that's "video-gamey" and one that is not? Is it in the structure, the tonality, or is it always something in between? Ponder this -- and also reminisce a lot about snow -- at our poorly-lit campsite while we search for the melodies that truly capture the pivotal moments of our lives.
