xmas song的完整歌詞如下：
男：
Wish all the things that you desire
Snow is falling, brighter than the stars
On this Christmas day, with you by my side
And every time I hold you close
And when you give me everything
You know that I'm so glad that it's Christmas
女：
Merry Christmas, happy New Year
Wish that you could see what I can do
Candle lights, dance in the snow
You're the one I love most this time of year
男：
All the angels sing, heaven's on high
Now I know that life's like a song
That's why I sing
Every time I hear a Christmas melody
It's you and me forever and ever
女：
Merry Christmas, happy New Year
Come on, let me hear you say Merry Christmas
It's not just a holiday, it's a way of life
I hope that you will remember my name
And that you'll always be mine on Christmas day
合唱：
Every time I hear a Christmas melody
It's you and me forever and ever
Merry Christmas, happy New Year
It's not just a holiday, it's a way of life
So let the music play, let the memories stay
Merry Christmas, happy New Year
To the world we belong, together we belong
Forever and ever, Merry Christmas.
