[Verse 1]
Sweat falls down my forehead
Think I'm nervous, standing next to you, mmh
Jagged heart's been stolen
But on the surface I try to play it cool

[Chorus]
I know
Shoulda let you, let you go
I know
Shoulda loved you, loved you more, oh
I know, I know, I know, mmh-mmh
I know, I know, I know

[Hook]
I know!
I know, I know, I know
I know, I know, I know

[Bridge]
Oh-oh
Bring your love right back
Bring your love right back
Oh-oh
Bring your love right back
Bring your love right back
Don't give up on me
Oh, I, I, I
Don't know how to act
I know, I know, I know
[Verse 2]
Rain falls down my window
In September makes me think of you, mmh
Tears all on my pillow
I see your shadow in this empty room

[Chorus]
I know
Shoulda let you, let you go
I know
Shoulda loved you, loved you more, oh
I know, I know, I know, mmh-mmh
I know, I know, I know
Don't give up on me
Oh, I, I, I
Don't know how to act
I know, I know, I know

[Hook]
I know!
I know, I know, I know
I know, I know, I know

[Chorus]
I know
Shoulda let you, let you go
I know
Shoulda loved you, loved you more, oh
I know, I know, I know, mmh-mmh
I know, I know, I know
I know!
