12+, while not the full story of a station, is directly correlative to the total ## of listeners to the station. To pretend otherwise is to simply spin, spin, spin. The 12+ cannot be dismissed as simply for people doing Monday Morning QB'ing. Theres a lot of information that 12+ can tell you about the market, where the overall audience tastes are going.
The fact is that the WAVF 12+ cume (the total number of bodies listening) is way way down.
96 Wave may have been the sound of Charleston, but now its only the sound of about 2-2.5 share of Charleston. 3+ share of folks have gone away in 5 years. Heck perennial also-ran 98 Rock had them beat a couple of books at one point. So, your perception of 96 Wave is based on what they were, not what the radio listening audience is saying they are now.
