@fats2drv I'm happy to look into this.
The next time this happens, can you please make note of what station is playing when a Christmas track plays?
When listening to Shuffle, you can view which station a particular song is from by scrolling to the bottom of the Now Playing screen. A banner will appear at the top of the window. It should say "[Station_Name] Radio," and then the name of the track.
If you'd like to see a picture of where that info will be located, check out my post on this thread: What station is playing while in shuffle mode?
Let me know what you find out.
