I'm actually little surprised to see Jack doing so well.. In many areas the Jack-FM format is either dying, or already dead. Here..it seems to be holding its own. I just moved to Nashville, so I'm still pretty new to the area and just beginning to get the feel for whats on the radio dial, but it seems to me that Jack is a little stale.. For a variety station, they seem to have a very limited play list.
I moved here from Milwaukee, where we have a "Jack" type station, called Lake FM (WLWK 94.5fm), they play everything from the 60's - now. You could litterally here The Beatles "Hey Jude", followed by a ABBA song, and then a current track. I'd love to see Jack add more on both ends, dip more into the 60's and 70's tracks and add maybe some more currents.
Also...a Mix station at number 1?? I would of just assumed a country station would take the top spot!
