Can't help with myself but my favorite christmas track is old, good Mariah Carey – All I Want for Christmas , i know i know - sooooo pop, but its not sad melodic and bells in background...mmmmm..... crazy and sing loud together other in better than Wham (almost every song which i havent listened billion time is better than Wham) is Latvian group Cosmos ( say what u want i say almost all of them are gays), accidentally got but liked this way they play it without any instrument .Cosmos – We Wish You a Merry Christmas - if can try to get this track.
