Well, the Christmas music started at 12:02 AM Friday morning by my watch. There doesn't seem to be any real pattern to it, at least not that I could notice. We might get one Xmasie song, then bunch of regular, then one Xmasie, back to regular. Or we might get a couple Xmasie songs back to back, or with only one regular song in between. Of course the selection isn't very big yet, so I heard basicly the same songs both Friday and Saturday night.
At least I'm on vacation this coming week, so I'll be able to manage to avoid the Xmas stuff for the most part for one week.
