Wow, great work Dan. I was engaged from start to finish, and had a huge smile on my face at the end.
If this is the remix then I think there could still be a bit more depth to the piano, the other elements are so rich that the piano needs more depth to really be the hero. The more I listen, the less it is an issue for me, so I think those listeners that come to the song for the first time are going to notice this more.
Just to reiterate, this is just a brilliant song and I am in no way canning what you have accomplished. This is my third listen and it gets better every time. That is the sign of a good song for me.
My wife agrees, no drums. (What is it with wives and drums?).
