Another potentially useful datum:

All House genre tracks dumped into a playlist, sorted by composer (my 'date added' column): works EXCEPT 2023.01.23, and 2024.10.30, both sort out of order. 2023.01.23 weirdly don't sort next to each other.

unicode characters are normal for the correctly sorted entries,

but also the incorrectly sorted ones, so it looks like it's not a characters issue (I've typed all of these manually so inserting unicode seemed unlikely but just in case)
