2015德国最感人圣诞节广告背景音乐是什么歌曲?? 歌曲为广告量身打造，目前没有市面还没发行。
歌名：Dad
歌手：NEELE TERNES
广告中歌曲的歌词：
I never told you how
How much you mean to me
What in the world I would do
I just never made it through to you, oh, to you
There goes a day, there goes a week
So many goals I had to reach
The more I did, the less I cared
The more I miss the love you've shared
If life is a song, somehow it's sad
I don't know the words without you, Dad
You've been on my mind all the time
And I'm missing you
Home used to be just some walls that I know
But the truth is home means nothing without you
Truth is my home means nothing without you
