They are still like an AC, just very gold leaning, which is increasing. If you look at the Mediabase chart on AllAccess for WXLY you can see how the currents are dropping.
If AC listeners don't like the gold lean, then yes Chick FM or maybe 101.7? I know Y started going AC'ish around early 2006 to start going after Sunny, but still played mostly 60s-80s. When Sunny flipped, they went straight AC but still played a lot of older music. If Sunny were still here, I would think they would be doing worse...but would they have transitioned to AC if that had not happened?
Y102.5 is interesting. They evolved from oldies to classic hits to AC from 2005-2007....there was never a flip or overall station change. Their logo is still the same even.
