Oh. My. Freaking. God.
This has to be the best track you have done so far; The Path Within is taking second seat until you do something better!
I have to agree with some of the other reviews; the piano is somewhat flat, and could do with a touch of reverb, not that I'm adding anything new here. Where to find a good choir, you say? The best I have heard so far is on GarageBand, though you have to play about with the attack and drag it foreward so it's in time <subliminal>get a Mac get a Mac get a Mac...</subliminal>. But seriously I don't think there is anything you can do to this melodically; I'll leave the techy stuff to other people!
Don't you ever stop, you hear me!?
