oh this is easy.
TFJ: Sinful for Numb, put The Family Jewels on all versions [i wanted to include Bad Kidz and Jealousy but i honestly could not figure out which songs i would cut from TFJ, it's so solid]
EH: Scab & Plaster for The State of Dreaming, Miss Y for Valley of the Dolls, Electra Heart for Living Dead (from the UK Version) [none of these songs are bad but i just love the unreleased's more]
Froot: just put INHA on it since it has so few unreleaseds
L+F: Water Under the Bridge (2018) for Orange Trees, Demons & Angels (2018) for No More Suckers, Please Don't Call Me (Final) for Life is Strange [i would also put Holiday somewhere if it was more polished]
