I found an old post where you got excited when "Seguaro" played as a BTF song during a J flavor in 1993 due to an error since you never heard it past the :53 mark before. For a lot of people, that was a blast from the past, previously regularly playing on J flavor LFs in 1990 and 1991.
Yah, I was surprised to discover that "Seguaro" was played before I started watching.
There's something else I've noticed, consistently, "Outside Solaris" by "Clifford Marshall Van Buren" played as an M flavor, but consistently used the L flavor narration, do you know what happened? Did it eventually play as an L with the L narration, was the narration eventually corrected for the M or did it keep playing as an M with L narration? And do you know how that song worked on the 3000 with its narration?
