Rory, my beloved Great Dane has become obsessed with....?

Chrismtas music, but especially George Michael's rendition of "Last Christmas". He barks until I put Christmas music on---and he his most happy when this Christmas clic is played. He just beams and is content. How do I stop this horrible trend from continuing. Last night, I had to listen to that dumb song over and over---plus a few other "clics", including O Tannenbaum and The Twelfth Day of Christmas (Elvis). I cannot take much more of this!
