Searching for a certain song!

[L1aRx]

Hi, I'm quite annoyed because I can't find this one song, i never knew the artist so i don't know that either. (also, not sure if i'm even posting in the right place, sorry!)

well it's a japanese song that i heard on one of the music station episodes that ayu was on. it was by a female artist, and sounded very christmas-y, or it was a christmas song. it was maybe on one of the specials, but i'm not sure about that. and it's probably one of the winter episodes. also, it might have been 2007, 2008, or 2009, but more in the earlier years i think.

omg! i hope to find this! thank you's!
