Christmas songs -Best versions

So I'm a little late in the season for this topic, but I'd still like to hear your choices.

List as many Christmas songs as you want and which version (artist/group) you think did the best version of all time.

I'll start with a song I've never particularly liked, but thanks to White Heart, their version of "Little Drummer Boy" is excellent and by far the best version of that song ever recorded.

What about you ? List some Christmas songs and which version (artist/group) did THE BEST version of those songs in your opinion.

I can hook you up with the worst version of "O Holy Night":

Not a huge Christmas music fan myself but I really like this version of "Mary Did You Know" by Kutless

This one of my fav versions of this song:

Nice ! I thought I'd get a bigger response on this thread. Again, I must be a little too late in the season for this topic.
Maybe next year I'll start a thread with a list of several classic Christmas songs, and people can pick and choose the ones they want and add which version they like the best.

I like Gary Hoey's version of You're a Mean One, Mr. Grinch.

Liberty 'n' Justice and Grave Robber did a good version of the Grinch song:

Rock Power Praise: Christmas Hymns is just about my favorite Christmas album of all time. Especially since I'm not really into Christmas music, with the exception of a few songs.

O Come, O Come Emmanuel and O Holy Night are two of the few Christmas songs that I really like. And that's only if they're done right.

I'm torn. I've always loved this one:

but then there's this version:

I have always LOVED the Viva Voce version !  It totally rocks !
Vol 2 was the first "Happy Christmas" I bought - love almost every song on it.

O Come, O Come Emmanuel by Tim Bushong is now a new favorite:

This would be my list. I'm limiting it to (relatively) hard music and standard Christmas tunes (ie, no originals, medleys, etc) so there's at least 2 to compare. LOL Note that there have been several metal Christmas albums that I don't have that have been released since stopping my show.

Angels We Have Heard - Adam Again (Hon Mention: Archer <- No, really!)
Away in a Manger - Gary Hoey (Hon Mention: Christmas Rock)
Carol of the Bells - TSO (Hon Mention: Pastor Brad & BWC Studios)
Deck the Halls - Ted Nugent (Hon Mention: Gary Hoey)

I'd have to agree with Theocracy's version of O Come O Come Emmanuel with Eulogium's version not far behind.  And Frost Like Ashes' bit of that song in their Let All Mortal Flesh Be Silent is amazing considering how high Sebat sings it  

Seeings how much I like Topshot's taste in music (I love almost everything he's played on Rocksalt) I'll be looking up the songs on that list for next years Christmas mix...
