I have a couple of friends who work for record companies in Nashville and they say that it is widely known that Brad Cotter is "difficult" to work with. Apparently, he has been trying to make it in the industry long before Nashville Star, but has a bad attitude that people just didn't find appealing. Now that he won NS last year, he has become even more "diva-like" and has turned off a lot of radio station promo people, A&R people, etc. b/c of bad interviews, demands, etc. Now, since I don't work in that industry any longer (used to when I was in college in Nashville), I don't know for sure, but my friends are reliable sources for the scoop!
I live in Atlanta, a pretty large country radio market, and they hardly ever play Brad's music. I also think that George Canyon should have won last year!
