Wow.
First off, this is easily the best song I've heard on this site (and from a great number of other places) that I can remember. Maybe its the best I've ever heard. I love the jazzy feel of the horns, the layered electronics, the great bass stuff, the percussion, the voice-everything is pretty much perfect. Its alot of stuff, but its put together perfectly and I really needed to listen to it a couple of times before I felt like I heard everything-and that is what makes a great song in my opinion. You really vary it up too- the beginning is different from the middle and the end is different from the rest. But its not random different, and that really shows how much time you spent on this. Honestly one of the few songs I've felt compelled to put on my ipod and listen to from this site.
I do hate you for not finishing the ending though. :/
Anyways, amazing work. Let me know if you finish this, certainly.
