recordings wanted...

first, of overtly religious music which would not be out of place at a Christmas Day celebration. Music which has not been overplayed to death is much preferred; explicit references to the nativity of Jesus are not essential.

second, of similar music on overtly pagan themes. Bonus points in this category for using the same tune as something you suggested in the first category, and for explicit references to gods who got syncretized with Jesus. (Someone somewhere must have recorded a praise song for Mithras...)
