I know it's "The Most Wonderful Time of the Year" etc. etc. But we don't all love it, and some of us go out of our way to avoid it.
If you are one of the someones, Rumbled (a simple location search will find it) is a Christmas free zone. The caveat I will place is hat the music is from a public stream. I haven't heard Christmassy stuff, but I can't guarantee that they won't.
And before anyone gets annoyed, this is neither cultural nor religious. It's simply an alternative.
