As I started watching "13 Reasons Why" in 2017, did I focus on the unraveling mystery, dark themes, or compelling acting? Yes. My initial thought, however, was, "If this series had aired 35 years earlier, 'Mammagamma' by The Alan Parsons Project would have been an appropriately grim theme song for it."
Perhaps I don't consume TV shows exactly how everyone else does. I still think that instrumental fits the general mood of the series, though.
