Maybe it has to do with fan base? Country fans are more accepting and don't really care, as long as it's mellow, easy to listen/dance to, and the singer/group don't sound like cats on wooden fences...
Rock music has more of a reputation with getting people off their feet and really getting into it, so many stage personalities and ways of singing as well as the music sound altogether. So the fans expect more out of the groups...maybe...?
Ugh, I know what I'm trying to get at, but it isn't working out. Let me know if this is making any sense, will ya?
