I like "Nightingale" more too, but "Warrior" has over a million views on YouTube + it's been seen hovering in the 800s on iTunes + it once had a 0.080 AI on radio like a month ago. It obviously has more potential.
Spill the true tea sis
I still don't get the love for Nightingale & Two Pieces here while clearly Warrior has proved that it has way more potential than other ballad in the album (and the most classic sound)
