Apparently, it's some sort of remix of a Christian Song called O Come, O Come Emmanuel. I don't know if I'm allowed to post this here. All copyrights belong to Tudou. ¸»¹óÃÅÓ¢Îĸè_ÔÚÏßÊÓƵ¹Û¿´_ÍÁ¶¹ÍøÊÓƵ ¸»¹óÃÅ
Wow, you found it! Everyone is scrambling over the Internet to find this song! Everyone's typing in parts of the lyrics to find it. By the way, do you know who sang the remix?
Enya sang the original song which actually sounds way different than this one. You can search the Enya one from Youtube. It was pretty tough to find, had to search through some Chinese forums.
Found it! It is by Enya, called o come, o come, emmanuel (CD Version): http://detailzsoft.blogspot.com/2009/11/enya-o-come-o-come-emmanuelcd-ver.html
