《因你而在》的中文歌詞如下：
因為你而存在
當你在我心中徘徊
我知道這就是我所期待的未來
你的笑容是我最美的風景
我願意為你等待
不管世界多么的黑暗
因為你而存在
因為你而改變
你的出現讓我的生命更加完整
因為你而存在
因為你而愛
這份感情如此真實強烈
就算風雨再大
我依然選擇相信
因為我們同在一片天空下
雖然夜的黑時刻襲來
可因為有你在身旁我就有了方向和力量
因為你而存在，因為你而改變
因為你是我的整個世界整個宇宙的寶貝蛋蛋蛋
為你唱這首隻屬於你的歌頌的歌旋律要強烈到此結束之前再轉一次角...等你回來...我為你而存在。
英文版歌詞為：
I exist because of you.
When you wander through my heart,
I know this is what I've been waiting for.
Your smile is my most beautiful sight.
I'd wait forever for you,
despite the dark, uncertain world.
I exist because of you.
Because of you I've changed.
Your presence fills my life with meaning.
I exist because of you.
Because you love me this way,
It's such a true and real emotion.
In spite of all that may come our way,
I choose to believe.
Because we share the same sky.
Though the night may bring its darkest hours,
You're there beside me, giving me direction and strength.
I exist because of you.
Because of you I've changed.
You are the whole world to me, baby.
為你唱這首隻屬於你的歌頌的歌，旋律要強烈到此結束之前再轉一次角，等你回來，我為你存在。
