The iTunes snippets prove my earlier suspicion that Roar is one of the weakest songs she's made this era. 
 
I don't like the verse production on Legendary Lovers but it sounds like a smash. 
Birthday is very cute and 90s like WOA but nothing special. 
Unconditionally is extremely underwhelming. Will be deleting. Same with This Is How We Do. 

International Smile is alright, but again nothing special. Possible delete.
Ghost is promising, the full song should be good.
Love Me is boring. Delete. 
This Moment is some kind of 80s ****. The chorus gives me Xtina teas. Reserving judgement.
Not sure at all about Double Rainbow.
By the grace of GOD indeed. 
 
Spiritual I use.
It Takes Two and Choose Your Battles meh.
 
Walking On Air is still the best song off the album.
 
I like that she's using her vocals so much better than she did on TD and her writing has improved. Almost every song is roughly 3:30 though and pretty generic, so she's sticking to the same formula and it's working commercially obviously but it isn't much growth.
