It's already been one hell of a day and it's only 5:30, but this song almost made me cry. It's quite beautiful. It's beyond the league of modern day composers and my vote is for its regard to be of the highest caliber. You're scratching at the door of musical perfection.
The flow is precise in a way that gives the song almost a life of its own; a breathing pattern.
The piano and added heartbeat create the illusion that one is already familiar with your song, even on the first listen. Great instrument choice, classic.
Your rhythm is slow, broad, and stagnant; yet forcefully moving in a great way.
Overall, a beautiful song to say the least and I feel that it will never fit in with the rest of NG, but it certainly shines here.
