Secret Together的詞曲由Avril Lavigne與Dr. Luke等人合作完成，以下是其歌詞：
I feel it in my fingers
And it tingle in my toes
My body's humming
And my nerves are buzzing
Yeah, I feel it, yeah
My mind's been lifted off the ground
You know what it is, it's the secret together
Secret together
Secret together
Oh, oh, oh
Oh, oh, oh
Oh, oh, oh
Oh, oh, oh
Oh, oh, oh
I'm feeling it in my bones
And it's all around me
It's a feeling that I can't explain
Yeah, I feel it, yeah
My body's electrified
You know what it is, it's the secret together
Secret together
Secret together
Oh, oh, oh
Oh, oh, oh
Oh, oh, oh
Yeah, I feel it in my feet and up my spine
It's a feeling that I can't shake it loose from my mind
You know what it is, it's the secret together
Secret together (secret together)
Secret together (secret together) (oh)
Oh, oh, oh (oh)
It's the rhythm in the beat that we feel now (secret together) (oh)
I got this feeling and I don't know what to do (secret together) (oh)
This electricity moving through my every muscle and every single fiber of my being (every single fiber) (oh) yeah (oh) 歌曲的高潮部分副歌歌詞為：Yeah, I feel it in my bones (oh) Oh, I got this feeling and I don't know what to do (oh) Oh, oh, oh (oh) Oh, oh, oh (secret together) Oh, oh, oh (oh) Oh, oh, oh (secret together) Oh! 整首歌的旋律輕快，歌詞充滿激情，讓人感到興奮和愉悅。 歌曲表達了男女之間的激情和相互吸引，是一首充滿活力和情感的流行歌曲。
