Just had the joy of hearing this on Radio 1. It's like someone put the original, Mistletoe and Whine and the bells from Santa's sleigh into a blender and this is what came out.
Seriously did someone somewhere not have the sense to stop them and say "look guys, this is really really bad". Shoulda just re-released the original and it would have probably sold tonnes from people downloading it from iTunes for their iPod/iPhone/iPad/iWhatever-else-has-an-i-on-it.
