《Lost in Echo》的歌詞如下：
女：
Chorus:
Lost in echo
Can't find my way out
Can't get back to you
Verse 1:
漫步在空蕩的街道
回憶像風一樣吹過
那些曾經的誓言
如今都成了泡沫
Chorus:
Lost in echo
Can't find my way out
Can't get back to you
Verse 2:
時間在不停地流逝
我卻在原地徘徊
你的影子在風中搖曳
而我卻無法觸及
Chorus:
Lost in echo
Can't find my way out
Can't get back to you
女：
Bridge:
Why do I keep on searching?
For something that's lost forever
I know I should just let go
But my heart won't let me stop
Chorus:
Lost in echo
Can't find my way out
But I know you're not coming back
So I'll just have to move on
男：
（重複副歌）
You were just a dream in my life
Now I have to face reality alone
But I'll always remember you, my love
And I hope you can find your way back to me someday.
（重複副歌）
合唱：
So lost in echo, but I know I have to move on.
