《We say hello》的詞曲由瑞典歌手Zara Larsson完成，中英文歌詞如下：
中文歌詞：
Hey hey hey
你好啊
是不是所有的人
都曾經遇過一個人
讓你心跳不一定
會加速運轉
你總是隨著風氣
來來去去
讓我無法捉摸不定
Yo Yo Yo
喂喂餵
我們是不是在哪遇過
你總是讓我感到熟悉又陌生
所以 我們要怎麼認識一下呢
Oh Oh Oh
Oh Oh Oh
這樣的日子我早已受夠了
這樣的日子我已經過了好久好久了
不過就算了 我現在已經過得很好啦
我現在已經過得很好啦 很好啦 很好啦
英文歌詞：
Hey hey hey, have you ever met someone
Who makes your heart beat a little faster,
You're always on my mind,
Coming, going, making me so hard to find.
Yo yo yo, could we have met before?
You always make me feel so familiar, yet so unknown.
So how should we get to know each other better?
Oh oh oh, oh oh oh, I've had enough of this.
I've been here for too long, waiting for my turn.
But it's okay now, I'm feeling good,
Feeling good, feeling good, feeling good about myself.
