據悉，蔡依林是Hardwell第一位合作的華語歌手，雙方都十分慎重，前期溝通及錄製長達3個月。蔡依林不僅在歌中展現低沉唱腔，更首度嘗試陽剛味重、派對節奏的電音曲風，歌曲一經曝光，蔡依林的`電音Style和磁性唱腔令諸多歌迷驚歎不已，有歌迷留言稱“抖腿迴圈一百遍，嗨到一晚上睡不著”，更有電音樂迷表示不敢相信自己的耳朵——“這真的是蔡依林的聲音?”蔡依林稱，計劃於今年發表的新專輯正在按部就班地籌備當中，她將會有很多突破性的嘗試和更符合當前人生狀態的表達。

When your cold and your broken
Like your lost at the sea
Follow me in this moment
And be free
So don‘t look down you gotta wait
Don’t worry now we can escape
When you don‘t know how to go alone
We’re stronger now than on our own oh oh
We could change the world tonight oh tonight
If we are one
Cause we can change the dark to light oh to light
If we are one
Woah oh oh oh oh oh
Woah oh oh oh oh
If we are one
When your cold and your broken
Like your lost at the sea
Follow me in this moment
And be free
So don‘t look down you gotta wait
Don’t worry now we can escape
When you don‘t know how to go alone
We’re stronger now than on our own oh oh
We could change the world tonight oh tonight
If we are one
Cause we can change the dark to light oh to light
If we are one
Woah oh oh oh oh oh
Woah oh oh oh oh
If we are one
If we are one
Woah oh oh oh oh oh
Woah oh oh oh oh
If we are one
