《greatest day》的歌詞全文如下：
I wake up in the morning
I stumble to the window
I'm wondering what's so different
A million people running
They're shouting for no reason
The best is yet to come
You feel it in your body
You feel it in your bones
It's a greatest day ever
It's a greatest day ever
You feel it in your body
You feel it in your bones
It's a greatest day ever
It's a greatest day ever
The sun is shining brightly
The birds are singing sweetly
The world is waiting for you
It's a greatest day ever
It's a greatest day ever
It's a greatest day ever
It's a greatest day ever
I take a deep breath in and out
And I'm feeling alright today
And I'm feeling alright today
And I know it's gonna be alright
You feel it in your body
You feel it in your bones
It's a greatest day ever
It's a greatest day ever
You feel it in your body
You feel it in your bones
It's a greatest day ever
It's a greatest day ever
你醒來在早晨，
我踉蹌到窗前，
我在想有什麼不同。
一百萬人在奔跑，
他們毫無理由地叫喊，
最好的還在後面。
你身體裡感到它，
你骨頭裡感到它，
這是最棒的一天，
是前所未有的最棒一天。
你身體裡感到它，
你骨頭裡感到它，
這是最棒的一天。
是前所未有的最棒一天。
陽光燦爛耀眼，
鳥兒歡快歌唱，
世界在等待你。
這是最棒的一天，
是前所未有的最棒一天。
