Well, other than that sagan was involved in that record, no, not as far as I know. The record contains greetings in 52 languages, and a whole bunch of random pictures from all over the globe as far as I recall.
Voyager itself is also really quite slow (compared to the Arecibo message), it hasn’t left our solar system properly yet, being somewhere near the heliosheath. I did some looking at it when I first saw Sagan mentioned, but couldn’t find anything that holds a solid tie to either Waking Titan or NMS.
That being said, it may hold some reference to cassette tapes.
If it is, this could be somewhat interesting: “The remainder of the record is audio, designed to be played at 16⅔ revolutions per minute.”
Edit: Notice how that is the number 16 again? Also, while I believe ppl tried to speed up/slow down the tapes by a little, I’m not sure if anyone went all the way and speed it up by that much.
