Now that's a swining song you put up there...
Let me say first, sorry for the (kinda) late review, new year's business etc. Speaking of new year, I listened to the English new year's celebration show and there was some real quality work there. To be honest, this could belong there.
I have forgotten the name of that program (I'm quite ashamed of that), but I've heard that getting a feature on that show is more of an honor than to score a #1 hit in the USA, you see what I'm getting at?
This is one of those songs that is calming, yet energetic. I think you should have hired a female singer to sing in this kind of song, if that would be possible :P
The song started good, apart from the fade-in effect, what wasn't that much of a letdown, but just starting off as a regular jazz-like song would have been better, I believe.
After that, all the instruments, which were playing different melodies (piano and others) were all blending in perfectly and kept the listeners attention; the song wasn't boring for one moment.
Later on, when the wind instruments started, this song really got deep, I loved that, but to be honest, the song could have lasted a LOT longer.
You have done something great here and if you decide to make this, or another upload much longer, I'll be sure to add it to my list of best songs (currently 209 songs with over 38 hours of length) and I'm serious here. Almost no NG audio portal upload ever made it there. Not even all of my favorites on my userpage have.
Anyway, I believe the song ended too abrubtly and because it's not a perfect song, I'll give this a 9/10 and so a 5/5, but this has limitless potential. Keep it up and SEND ME YOUR NEXT SONG!
