I have been selflessly scouring the database at Lala to make you this Christmas Mix. ;-)
I was inspired by the Sufjan Stevens Christmas 5-disc CD and there are a lot of his songs on here (how many other people in the last ten years have 5 Christmas records?). But, there are also others, too. There are some nice vintage songs in the middle and although it is generally pretty mellow, it picks up a bit near the end. I hope you enjoy it.
[Edit: Bummer. Didn't realize you had to be a member to listen. Still...I encourage you to join. It is free and it is a great way to listen to anything you are curious about.]
