Generally, I like Christmas music. I like old, croonery, sleighbelly Christmas tunes. Not so fond of the pandering high melodrama of Mannheim Steamroller, the unnecessary showmanship of Mariah Carey or the gutter humor of receiving a beer on the first day of Christmas. (Okay, maybe that last one gets a pass).
One I like: "It Came Upon A Midnight Clear" - almost too Protestant, I still like the gently surprising deviations from the major scale.
One I dislike: "Silver Bells" - for its slurring, drunk (regret it in the morning, not just a little giddy) melody.
