I'd guess "æternum" for that track title, I remember some math books in college saying "ad æternum" a couple of times, meaning "eternally doing this step" or something like that
Edit: oops nevermind, I hadn't seen the HQ crop where you can see the last "a"
On another note, I'm kinda glad she deactivated Instagram comments, I'm pretty sure that second cover would have caused a lot of... Trouble
