Tune for the Weekend! - Dec 19th

Image by stephen.spillane via FlickrWell its the last weekend before Christmas and I think the song I have picked for this week's "Tune of the weekend" is one that will be played in clubs and bars up and down the country this weekend. In fact on the last two Friday nights I went out I heard it! It is another one of my favourite christmas songs and one I use to drag himself out to dance for. It's by Mariah Carey and I think yoy can guess the name of the song!
