So reading the writeup, this song makes a lot more sense.
I agree with what others have said about the last note, but that has been addressed so I won't go there. One thing I felt though is that the backing to DA's vocals is a bit too loud and drowns out the vocals a bit.
The second half of the song is excellent in contrasting a touch of sadness to the first half, and I feel that's where this song really shines (that being the second half), as the main part with the source is used in a more uplifting manner than the original.
Great job trio!
