I like to get an early jump on the christmas music. If I don’t I tend not to get it out of my system till mid to late January (which people find weird). Today I found this site.
If you can’t tell by the URL, it plays christmas music 24/7. And also 365 days a year. You can also find it oddly placed under the religious section of your itunes radio library titled Christmas 24/7. If only that applied to more than just the music!
Also remember that a lot of people are still in the scrooge mood at this time of year. Make sure to wear headphones while listening around these types.
