I haven't seen a link to the song itself anywhere, but the stations that had played it are WJXB (Knoxville, TN) and
WYJB (Albany, NY). I checked them out online and happened to hear it.
The websites are
www.b975.com (WJXB) and
www.b95.com (WYJB)
You will probably have to listen a while before you hear it come up in rotation.
Here's a blurb I saw from the website of reliant music "Writer/producer Ryan Stewart has produced a US radio version of “A Woman’s Heart” for EMI Music’s platinum artists Celtic Women."
