That’s like Houses Of The Holy by Led Zeppelin. Houses of the Holy was the title of their fifth album, but the song Houses of The Holy was on their sixth album, Physical Graffiti.
There's also Roxette's debut album Pearls of Passion with the same-titled song not included among the album's original tracklist, being only released at its time as a B-Side to one of the singles. 'Pearls of Passion' would only appear in the album 11 years later with the remastered edition.
There's a similar scenario with the Doobie Brothers' album CYCLES. It was named after a song written by the bassist, Tiran Porter, that wasn't selected for the actual album. In fact he had so many songs rejected by the band over the years that it's a wonder he stayed with them as long as he did. He finally recorded the song "Cycles" for his solo album, and IMO it would have been a worthy inclusion on the CYCLES album if it had been properly recorded. (His solo version was very demo-like, with drum machine, etc.)
Anyway, I was hoping to see more examples of album titles that are utterly, bizarrely disconnected from the albums themselves. So far I don't think anything has topped my own first example.
