Here's the only good stuff about Xmas I can think of:
Late in life, classically trained singer and actor Christopher Lee (who is best known for playing Saruman in LOTR), discovered heavy metal and fell in love.
Lee grabbed some amazing musicians and started producing heavy metal music. Some of the music he created was Xmas themed...here is a snippet (check out the rest of his stuff too). Rest in peace you amazingly talented man.
The only other Xmas related thing I can think of sharing is this great song by Type O Negative. It is about Xmas being really shitty because people you loved to spend Xmas with are all dead. I believe this is something we should all reflect on during any holiday. Thematically this is of course...metal as f%$#. Rest in peace Peter. Enjoy:
