If she still has the rights to the music she made under capitol, the ones that will make the cut are probably;
All My Lovers Die
Descending
I Pray For Rain (she'd be insane not to)
Innocent Kind
Don't Forget
Downhill Lullaby
Maybe (probably not): guardian
My sad suspicion is that she doesn't have much more (if any) other than these. The other leaked songs are not really good, so Idk. I think the whole delay has been due to her not being finished or satisfied with the record. I also suspect she barely recorded any new music since 2019 — Guardian (2014); IPFR (2015); AMLD, DL, DF (2017/2018); Descending (2019) — Most of the other leaks are from 2015... so yeah, based on a decade of evidences since I've been following her and anticipating this album, I don't believe she ever had enough (good) material for the record other than these songs, and the main reason is that she probably got messed up with some bad stuff and has been dealing with the aftermath of that for some years, but I digress. Anyway, I'm rooting for her and I hope she gets to officially release at least All My Lovers Die & I Pray For Rain, because they're THAT good and genuinely instant classics (and Guardian as well). What a waste..
