Switching places on the dial for 103.1 and 98.5 may be the best thing for the Urban A/C format but it will just be another nail in the coffin for Oldies. Granted a lot of their numbers probably come from Lexington County but for decades now, the fastest growing area in Columbia has been northeast where the well-heeled, affluent professionals have landed in great numbers. Oldies will lose a lot of well-heeled, affluent professionals in this scenario UNLESS they can legally move the 98.5 tower, which if they could or would do, would make the whole switch unneccesary.
It will definitely be interesting if they put True Oldies on. I give credit to Brent Johnson and Bill McElveen for persuading corporate to keep it "live and local" as long as they have.
As far as their music mix, they tried to create a "Jack" type Oldies format. In my opinion, it has been met with mixed results. I'm not sure their older listeners really want to hear "thunder island" by Jay Ferguson. But you've got to bring in younger demos somehow, right? The Oldies format at first was doing a great job of "selling" older music to the following generations (subtley selling the idea that it was cool music in marketing campaigns, etc)but fell down on that job during the past 15 years. Too bad.
