I know a lot of people hate Christmas music, and when I worked at Borders, it drove me nuts. However, there are some music collections that I really enjoy! The Vince Guaraldi Trio (the guys who performed the Charlie Brown music) have some awesome Christmas stuff, and if you create a Pandora station based on Celtic Woman (holiday), you'll get some truly relaxing/festive music that's easy to listen to and enjoy. It's also great background music when you need to write a query (which I've been doing this morning, and with some success despite waking up late).
When I'm playing my music at work (which is an awesome perk!), I keep the Christmas stuff to a minimum. Usually, I pull up a Pandora Quick Mix with a handful of rock and/or ska stations, and then I add the Charlie Brown Christmas station. It's easy to enjoy that mix of music without my co-workers threatening to lynch me for over-indulging my perky Christmas Spirit!
I know it sounds weird, but I love Christmas. At least now that I'm not working in retail! I remember setting up our Christmas tree every year on the day after Thanksgiving, and we had the railing that we would put garland on, along with snow-flake ornaments that depicted each scene from the Twelve Days of Christmas. My twin and I (at ages 5-7 or 8) would then get the Christmas CD with that song, and we'd run up and down the stairs, singing along and pointing at each ornament as it's corresponding notes shrieked out of our lips.
I miss those decorations. And it bums me out that all I get to do at my apartment is one strip of garland with a handful of ornaments on it. If only my cat would leave a Christmas tree alone. Not that I have room for a tree in this tiny place.
