IMHO......No, there are already channels available on XM with a format like the River's Format. They carry WSIX because of Jerry House being a legend in the nations broadcast industry and he can pull ratings in any market. Over the past 25 years since "The River began it's CHR format as Y-107" it has had legends like Coyote McCloud pull good numbers. Woody and Jim are good, but Woody & Jim will never capture the magic that Coyote and Rhett did in the 80's and early 90's.
Clear Channel owns other CHR's like the River in other markets. The River has nothing to offer anybody outside the Nashville Market. This is just my opinion, but what the hell do I know?
