I never listen to holiday music unless I'm forced to via the store. Just not a big fan of it. Unless you count Halloween music, I listen to Halloween-style music all year round. But never Christmas music :x
I'm a Christmas fanatic, but I'll usually wait until December 1st to roll around before I start seeking out Christmas music. One of the stations on the radio over here has started its Christmas music marathon, and I checked out a few songs on the way home from work one day, but I'm sure once December rolls around, I'll be dialed in and jamming along.
