A song so transgressively powerful it made way for a whole new kind of rock and roll, and a cover that makes something old new again in the best possible way. Heart of Glass, originally by Blondie, covered by Nick Shoulders.

Outro music is Will Ye Go, Lassie Go/Wild Mountain Thyme from the Sinners soundtrack by Lola Kirke, Jack O'Connell, and Peter Dreimanis.

A song from a band that knows how to deliver on expectations, even when they're in an experimental period, and a cover from an artist whose hallmark is subverting expectations to brilliant effect. Sad But True, originally by Metallica, covered by St. Vincent.

Outro music is We All Die Young by Steel Dragons, in case you'd forgotten about the movie that captured the spirit of power metal.

A brilliant and beloved song from a band that had the right mix of magic to get it right, and a cover that provides a wild backstory. Build Me Up Buttercup, originally by The Foundations, covered by The Valentines.

Outro music is Baby, Now That I've Found You, also by The Foundations, because how could we not.

If you're going to have one hit on top of a prolific career, it's hard to do better. This week's song is unique and fascinating. I'm Gonna Be (500 Miles) originally by The Proclaimers, covered by Alejandra Ribera. You know you want to sign along.

Outro music is (Don't Fear) The Reaper, by Blue Oyster Cult.

A breakthrough moment in the history of Rock Steady puts us on a musical path that's both familiar and incredibly unfamiliar. A Message To You Rudy, originally by Dandy Livingstone, covered by The Specials, and by Skatune Network.

Outro music is Your Horoscope For Today, by Weird Al Yankovic, which lets us wrap the episode firmly back in Ska-Land.

A listener request brings us one of the classic songs of Rock and Roll with the most unlikely origin story, and we get to call out a music recognition organization that isn't the Grammys. The Twist, originally by Hank Ballard and The Midnighters, covered by Chubby Checker.

Outro music is Back In The Saddle Again, by Gene Autry, though Zach's suggestion would have been right on as well.

An early song that could have easily defined a band's career, but instead just gave us a glimpse of what was to come, and a cover by a great band that was out in the wilderness making some bad choices. My Generation, originally by The Who, covered by Iron Maiden.

Outro music is Roll Away The Stone, by Mott The Hoople.

A song that reestablishes a seasoned and successful artist as a new kind of force, and a cover that embraces musical complexity in a brilliant but subtle way. Heaven Is A Place On Earth, originally by Belinda Carlisle, covered by The Mayries.

Outro music is I Wanna Dance With Somebody (Who Loves Me), by Whitney Houston, because this song is inevitable.

Great lessons to learn from one of the all-time road songs, a cover that understands the assignment more than the song — oh, and Rich flubs his kids' birthdays, but that's OK, because we only recorded this on Father's Day. Life Is A Highway, originally by Tom Cochrane, covered by Rascal Flatts.

Outro music is Another One Rides The Bus by Weird Al Yankovic.

A classic that somehow remains a secret, and a listener leads us to a great musical discovery. The Ghost In You originally by The Psychedelic Furs, covered by Robyn Hitchcock.
