Whats the really nice christmas song?

Question

that they like have like 5 different voices you hear and its really slow. i cant remember it

Answer 1

Can you narrow it down a bit?  Celtic Woman does a lot of nice songs and I think there are five of them.  Or it could be a song from the Three Tenors - Pavarotti, Domingo, and Carreras - if it's men singing.  Are they men or women singing?  Is it a more modern song or an older one?  Can you remember any lyrics?

Answer 2

that's a lot of christmas songs..
