Which bells have the best jingle?

It's Christmas time again and that means that Christmas music will pervade the air in every office and retail center for a solid month, eventually driving many of us insane. Christmas music is definitely its own genre and this causes people to be extremely lenient with it (case in point: that freaking chipmunk's christmas song).

I always try to find something for the season that's still tasteful and, more importantly, "talent-ful." I tagged The Carpenters for their Christmas album, but I'm a bit of a classicist I guess. I'll always enjoy Bing and the like as well.

What do you think? What's some quality Christmas music? Help me out here, I need to diversify my seasonal ambient portfolio.
