Who was that rebel Yuletide music enthusiast?

Now that it's the Christmas season, how do you acknowledge it musically?  I heard someone blasting "Jingle Bell Rock" by Bobby Helms through an open window yesterday.  Although playing music that loud is usually ill-advised, it's nice to know that someone likes Christmas enough to want to crank up "Jingle Bell Rock."  Turning up the volume to 11, per Spinal Tap, isn't usually done with Christmas music, so it was refreshing to hear--for those 30 seconds, at least.
