歌詞如下：
Once upon a time
曾幾何時
I was of a mind to lay your burden down
我想要卸下妳的包袱
Leave you where you stood
讓妳留下來
You believed I could
妳相信我可以
You'd seen me done before
妳見過我那麽做
I could read your thoughts
我知道妳在想什麽
And tell you what you saw
說出妳所看到的
And never say a word
不要說話
But now that is gone
但這都過去了
Over with and done
壹切都結束了
And never to return
無法挽回
I can tell you why people die alone
我可以告訴妳，為什麽人們都孤單地死去
I can tell you why I'm shadow on the sun
我可以告訴妳為什麽，我是陽光下的影子
Staring at the loss
註視著失去的東西
Looking for the cause
尋覓著事情的原因
And never really sure
但心中永遠不確定
Nothing but a hole to live without a soul
不用心去生活，只會像空洞壹樣沒有意義
And nothing to be learned
什麽事都學不會
I can tell you why people go insane
我可以告訴妳，為什麽人會變得荒唐
I can show you how you could do the same
我會讓妳明白，妳就在做著這些事情
I can tell you why the end will never come
我可以告訴妳，為什麽永遠沒有結局
I can tell you why I'm shadow on the sun
我可以告訴妳為什麽，我其實是陽光下的影子
Shapes of every size move behind my eyes
大大小小的人影，在我的眼前走來走去
Doors inside my head bolted from within
我腦海中的門，從裏面反鎖上了
Every drop of flame lights a candle
每壹顆星火都燃亮了蠟燭
In memory of the one who lived inside my skin
是為了紀念那些，在我靈魂深處活過的人
I can tell you why people go insane
我可以告訴妳，為什麽人會變得荒唐
I can show you how you could do the same
我會讓妳明白，妳就在做著這些事情
I can tell you why the end will never come
我可以告訴妳，為什麽永遠沒有結局
I can tell you why I'm shadow on the sun
我可以告訴妳為什麽，我其實是陽光下的影子
Shadow on the sun
陽光下的影子
Sun, Sun陽光，陽光
