《So I Know》的歌詞如下：
I ain't saying much
I ain't got a plan
But I know you ain't the same
When your heart beats again
You ain't the same
When your heart beats again
Oh you ain't no boy
Oh you ain't no girl
Oh you ain't no boy
Oh you ain't no girl
Oh you know it
Oh you know it
Oh you know it now
So I know it now
Yeah I ain't saying much
But I know you ain't the same
When your heart beats again
You ain't the same
When your heart beats again
Yeah I know it
Yeah I know it
Yeah I know it now
So I know it now
(Chorus)
You're on your own now
But you ain't alone
Cause you're on your own now
But you ain't alone
You ain't alone now
You ain't alone now
Oh you ain't no boy
Oh you ain't no girl
Oh you ain't no boy
Oh you ain't no girl
Oh I know it now
So I know it now
(Bridge)
I don't need to see your face again
I don't need to hear your name again
Cause I know that love is real
And I know that love is fine
And I know that love is mine
And I ain't giving up my time
Now I know it now
So I know it now
(Chorus) x2
(Outro)
Yeah yeah yeah yeah yeah yeah yeah yeah yeah
Yeah yeah yeah yeah yeah yeah yeah yeah
I know it now
So I know it now
Yeah yeah yeah yeah yeah yeah
Yeah yeah yeah yeah
I know it now
So I know it now
Yeah I know it now
So I know it now
