My introduction to Hallelujah was via Malcolm Gladwell's podcast. A good portion of Season 1, Episode 7 (2016) was dedicated to the evolution of Leonard Cohen's song from 'forgotten B-side track' to the song that is commonly known and covered today.

The author of this submission mentions this podcast:
> On his podcast, Revisionist History, Malcolm Gladwell presents his theory on two types of artists: conceptual innovators and experimental innovators. Conceptual innovators create their best work early on in their careers.
Both this submission and Gladwell's podcast are based on Alan Light's 2014 book: https://www.simonandschuster.com/books/The-Holy-or-the-Broke... / https://www.google.com/books/edition/A_Broken_Hallelujah_Roc...
