Sam Harris sings here about a guy who is so brokenhearted, he feels he has lost his capacity to ever love again. He originally recorded the track in the band's touring van. Then the band went to the studio and added the vocals of a L.A. gospel choir. He recalled in a track-by-track commentary: "We got this gospel choir to sing on the chorus of it and that was the most incredible thing I've ever witnessed in my entire life; you know, seeing a whole choir of people sing these words that I wrote."
Mike Campbell from Tom Petty & the Heartbreakers played the slide guitar on "Sixth Avenue Heartache." There is a connection here - Wallflowers lead singer Jakob's dad, Bob Dylan, played with Tom Petty in The Traveling Wilburys.
The Frozen song "Let It Go" was recorded in 42 different languages for the movie's foreign releases. This earned it an entry in the 2016 Guinness World Records publication for "Most Languages Featured on a Single."
