A few comments, George..

1) HOW I ENVY YOUR VOICE! such depth and substance! it's just perfect for the genre in your collection of songs !

2) I agree with Kevin that the MIDI in your song sounds surprisingly good. I haven't spent any time messing with Sample Tank, but now you've got two of us looking at it. Maybe you should contact the company that makes SampleTank and ask for your commission!

3) regarding the production, mix etc... I'm not the guru in that department... but the vocals were right on top, nothing sounded muddy... I would be proud if I made a song that sounded that good (and I hope you are too)
