The the flip to Christmas music, I say "oy vey."
It would be silly for Clear Channel to flip WISX to Christmas. They're going to get some of the spillovers from people who think WBEN plays too much rock.
It would be silly to flip WYSP to Christmas if they're going to flip to sports. You don't flush out the audience between a rock format and a sports format. Too much overlap. If they're going to flip to AC, now is the time, but they should flip to year-round AC music, not to Christmas music.
