Tom; cclarry and Freddy J; Thank you for listening and your kind words.
Tom; Yes, I think the flanging is an artifact of the low resolution mp3, and Soundcloud's re-conversion, as its not present in the original wav file.
I used the mp3 converter in Sonar for the conversion, but at a low resolution, probably 128kbps for faster upload. Normally, for my own use I convert at 256 or above depending on the use. In future I will try higher resolutions for upload to Soundcloud.
Freddy JL; I don't think that the singer is trying to particularly sound "American", but here in Australia there are many "country singers" that make a virtue of sounding "Australian". While I have no problem with this, this singer does use his natural voice with no affectation, and if it does sound "collective", which I personally find more attractive than our own, then thank you for the compliment.
