Both for Category 1:
"I Want To Love You Madly" - Cake
(Anyone want to list the connection to Christmas lyrics? It's 1:27 into the tune.)
"I Wish" - Stevie Wonder
(I'm surprised that someone hasn't beat me to this one! Christmas reference is in the first verse. Go ahead and list the lyrics if you know it!)
Think outside of Christmas for Catagory 1, folks! What do you hear all year that has an obscure reference to Christmas? MC, The Robert Q. tune is PERFECT! The tie in with Rosemary Clooney is even perfecter!
