I'm a big fan of the Christmas Revels recordings -- one of my favorites is the Christ Child's Lullaby; the liner notes say it's translated from the traditional Gaelic song "Taladh Chriosta" from the isle of Eriskay. it's performed with Northumbrian pipes, concertina with a solo vocal -- positively haunting.

"My love, my pride, my treasure -- oh,
My wonder, new and pleasure -- oh,
My son, my beauty ever you,
Who am I to bear you here?.."

I don't know what the general feelings are towards the Revels around here -- might be like the Andrew Lang Fairy Tale collections, lol.
but -- there's at least a half dozen discs totaling approximately 6 hours of not-so-common songs of the season to break up the incessant repeats of "Sleigh Ride", "Winter Wonderland", and "Jingle Bells" which seem to be the non-denominational songs everyone covers and all muzak tapes are required by law to pump out in malls, I reckon.
