This is no joke.
Doctor Octoroc released a full MP3 album of NES-inspired Christmas songs called 8-Bit Jesus, and it’s really cool.
Check this out:
8-Bit Jesus
- We Three Konami
- 8 Days of Master Robots
- Ryu, the Red Nosed Ninja
- We Wish You a Merry Faxanadu
- Silent Knight Man
- Carol of the Belmonts

- What Guardian is Legend?
- Deck the Kremlin
- Icarus! The Angels Sing
- The Legend of Noel
- O Come, All Ye Vampires

Nice bit of tracks, eh!
If you know what each of these titles are referring to, you’re in good company. 
You can snag the album from iTunes for $9.99 or the 6-panel digipack (plus bonus track) for $12.00.
Best of all, you can listen to all the full length tracks on their website (wasn’t working in Chrome, I had to load it up in Firefox).
Love it! There’s also ’8-bit Christmas’ but rushcoil: http://rushcoil.bandcamp.com/
