A History of Rock Music in 500 Songs - This is one of my favorite podcasts, but I'm going to warn you it's not for everybody. The creator of this show, Andrew Hickey, is THOROUGH. A great example is the most reason episode about Hey Jude. Either you will love the concept of a 3.5-hour episode where 80% of the podcast is not about the song but rather the circumstances and lives of The Beatles, Yoko Ono, and the late 1960s music scene leading up to the creation of Hey Jude, or you will be furious that so much of the episode is about stuff that isn't the song.
