《All Day》的詞曲由Cody Simpson創作，以下是這首歌的歌詞：
Verse 1:
I'm feeling like a million bucks
Every time I'm with you
You make me feel like I'm on cloud nine
And I don't even know why
Chorus:
So all day, all day
I'm feeling like I'm in love
And all night, all night
I'm dreaming of your touch
Oh, every single moment
I'm feeling like I'm in love
Verse 2:
I wake up in the morning, it's on again
Girl, you know that you make me lose control
So why can't we just keep this going?
Yeah, forever, you and me alone.
Chorus:
So all day, all day
I'm feeling like I'm in love
And all night, all night
I'm dreaming of your touch
Oh, every single moment
I'm feeling like I'm in love.
Outro:
Forever in my dreams
Feeling so right.
Underneath the stars
Watching them shine.
Yeah, you and I
Got the whole night.
So all day, all day.
