If MNEK is involved I hope it's more Final Song than Never Forget You. I love NFY and all but she doesn't need another song like that right now, something a little more uptempo would be great, but not too uptempo like Lush Life. Somewhere inbetween.
The fact that Justin and Julia are involved either way though.

YAS. Power duo.
Back + Forth sounds like a single title, especially if it's stylised like that.
