She is sooooo smart at interpreting her vocals...I can tell how she softened her voice purposely because it's a male-female duet and she wanted their vocal performances to be distinct...because originally I expected her to sing it with more umph like he does
The song is longer than average right now tho. I don't have a problem with the song length; 3:43 is not that short. Especially by current standards. I suppose it feels shorter if you're seeking her vocals with her singing half the song. It wouldn't have hurt to have her do a bridge, but I don't mind the current arrangement.
I've outrun the fears that chased, they're standing still
I'm running still, I'm running still
And every voice that cried inside my head, forever drives
Forever drives, I kill the lights
