First thoughts:
While the other songs seem nice, I really think she'll find success if she releases these three tracks:
Unconditionally
Spiritual
Legendary Lovers
Based on reviews and snippets, I think the singles will be (in no order)
Roar
Unconditionally
Legendary Lovers
Birthday
Dark Horse
Double Rainbow
This Moment better be a single or I'm protesting in front of Capitol Records HQ, if the full song turns out to be as amazing as the potential I'm hearing in the snippet.
