Looks I got a bite! One of the sources I check had some results.

It seems like the user posted the song lyrics for the four new songs; from the sounds of it, they do own the album and transcribed it for their discussion thread. He/she also mentions something about years involved in the corners and trying to calculate something, which may imply that there is indeed more info included in the booklet (although it might only be timeline info).

Translators may want to look at that post more in-depth.
