Sweet! "A Holly, Jolly Christmas" is still on the list.
And "Rockin' Around the Christmas Tree" and "Jingle Bell Rock." 
Apparently, those singles get purchased, downloaded and streamed so much during the holidays, it's enough for them to place on the year end chart.
I only know five songs: the xmess ones, and Kate Bush.
