《冰雪奇缘2》的主题曲是《Into the Unknown》，其歌词如下：
```
Ah ah oh oh oh
Ah ah oh oh oh oh oh
Into the unknown
Into the unknown
Into the unknown
Ah ah ah ah ah
Ah ah ah ah ah
I can hear you
But I won't
I can hear you
But I won't
Some look for trouble
While other don't
There's a thousand reasons
I should go about my day
And ignore your whispers
Which I wish would go away
Ah ah oh oh
Ah ah oh oh
No
You're not a voice
You're just ringing in my ear
And if I heard you
Which I don't
I'm spoken for
I fear
Everyone I've ever loved
Is here within these walls
I'm sorry
```
