I haven't started any Christmas music yet for a few reasons. One, I don't have a huge amount of the stuff to begin with, and (how's this for "way overboard," lilburn radio?): one of the full-power FMs here has already gone, as you say, "wall-to-wall Christmas," to the point where Santa suits are mandatory dress for all full-time staff until COB Monday, December 24th, and their EAS test databursts have been replaced by jingle bells. Only Santa hats for the weekenders, though. A bit ridiculous, wouldn't you agree?
But back to KAPM AM 1670 and 95.7 FM...I'll probably start with a Christmas song or two an hour over this next week in an attempt to keep burnout at bay, then increase gradually as "the Day" approaches, but as for "wall-to-wall," are you kidding? I don't have enough Christmas music for a bathroom throw rug, let alone "wall-to-wall."
