《Mystery of Love》（爱的奥秘）是Sufjan Stevens为电影《请以你的名字呼唤我》（Call Me by Your Name）演唱的插曲，被收录于电影原声带。并于2017年12月1日发行单曲。其音乐视频于2018年1月4日发行，在拿坡里国立考古博物馆拍摄完成。
淡淡的旋律加上魔幻嗓音，诠释出电影的色调，既充满故事又耐听，让电影加分很多，甚至让听众一回想电影片段，脑海里便浮现该曲，堪称与电影合而为一。若电影本身是梦境，该曲则让电影更提升一个层级，到了仙境。当埃利奥和奥利弗前往贝加莫，在绿色山林中快乐奔跑和呼喊时，《Mystery of Love》响了起来，Stevens清甜脆弱的歌声穿过吉他和曼陀铃，几乎与耳语无异。该曲的歌词就像埃利奥的内心独白，捕捉了他内心深处的渴望。两位主角都知道，他们在一起的时光即将结束，这个夏天不可能永远持续下去，所以这一幕和该曲都充满了苦乐参半的味道。
Mystery of Love歌词：
Oh to see without my eyes
The first time that you kissed me
Boundless by the time I cried
I built your walls around me
White noise what an awful sound
Fumbling by Rogue River
Feel my feet above the ground
Hand of god deliver me
Oh oh woe oh woah is me
The first time that you touched me
Oh will wonders ever cease
Blessed be the mystery of love
Lord I no longer believe
Drowned in living waters
Cursed by the love that I received
From my brother's daughter
Like hephaestion who died
Alexander's lover
Now my riverbed has dried
Shall I find no other
Oh oh woe oh woah is me
I'm running like a plover
Now I'm prone to misery
The birthmark on your shoulder reminds me
How much sorrow can I take
Blackbird on my shoulder
And what difference does it make
When this love is over
Shall I sleep within your bed
River of unhappiness
Hold your hands upon my head
Till I breathe my last breath
Oh oh woe oh woah is me
The last time that you touched me
Oh will wonders ever cease
Blessed be the mystery of love
