Although this probably doesn't work for me (see entire post) I really like this idea.

I still got my Starred playlist from back when you couldn't like. Been using dual like and Starred ever since they added like list. Since Starred playlist still contains dates, I could retroactively do what you did. However there would be some months with a lot and some with (almost) none and I have a tendency to hyperfocus on certain genres/artists for a while which might split but not on exact start of month.
