WTF?

Which Animal did that? True Colours doesn't have a feature according to iTunes. I trust that.
The only way that could be true is if she provides uncredited vocals (because of contract) and someone who knows this has edited the Wikipedia page? But surely we'd know about this... I think it's a troll.
EDIT: Straight Into The Fire and Daisy say they feature Julia Michaels on Wikipedia (but not iTunes) and she's often an uncredited vocalist on many EDM songs (Surrender by Cash Cash, Invincible by Borgeous etc.) ... so it's a possibility. Not getting my hopes up tho.
