I've listened to "get into the spirit" 3-4 times now and I'm digging it more and more. It's sounds very much Halford band metal and nothing of a 'christmas song'...Ironically I could see myself getting pumped for some x-mas shopping just listening to that song... 
I encurage those to have another listen...maybe many.:)  It's a grovin song!!
