This is sort of a departure from the specific topic, but I have always felt that to fully appreciate the song Shine On You Crazy Diamond Pt VI - IX, you had to listen to the entire album Wish You Were Here. The second Shine On track just seemed to be an epilogue to the preceding 4 songs, fading in to start and then back out as it ended.
So it’s sort of on-topic; a song that had to be played in its entirety along with the full album to set it up.
I agree. I was never able to listen to just one track of a “concept album”.
