WRFY is interesting. As I posted some while back, they used to be a much more unique rock station, but lately they've gone to more a classic rock lean.
From what I gather, only a few currents an hour.
I remember a few years ago it was a totaly different deal, back in 2004. wasn't it in 2000 something like oh how did that go? "The best songs on the radio, Y102"?
I didn't listen during the CHR much, i wonder if there are airchecks around? From what i do remember, that didn't last long at all. i thought it was Hot AC not CHR though.
