[Verse 1]
The me that you used to know, I hope you forget about
Wondering where did he go, if you could just see me now
Hoping that you see that something inside of me's changed
(Everything's changed now)
Leaving behind me the old me and walking away
Oh, 'cause that was so

[Chorus]
Yesterday (Yesterday)
But I've moved on
Now I finally have a heart, finally have a heart
Of love where once was stone
And that was so
Yesterday (Yesterday)
But not no more
No, I'm never going back, never going back
To who I was before
And that was so
Yesterday (Yesterday)
That was so, that was so
That was so
Yesterday (Yesterday)
That was so, that was so, that was so

[Verse 2]
Let me be the first to say, I keep messing up as I go
I keep getting in my own way but the difference is now I know
There's something inside me that loves me no matter what (No matter what)
What I do and go through is not who I am because
That was so
[Chorus]
Yesterday (Yesterday)
But I've moved on
Now I finally have a heart, finally have a heart
Of love where once was stone
And that was so
Yesterday (Yesterday)
But not no more
No, I'm never going back, never going back
To who I was before
And that was so
Yesterday (Yesterday)
That was so, that was so
That was so
Yesterday (Yesterday)
That was so, oh-oh-oh

[Bridge]
Never going back
No, I'm never
Never going back
No no I'm never
Never going back
No, I'm never
Never going back
[Chorus]
That was so
Yesterday
But I've moved on
Now I finally have a heart, finally have a heart
Of love where once was stone
That was so
Yesterday (Yesterday)
But not no more
No, I'm never going back, never going back
To who I was before
And that was so
Yesterday (Yesterday)
That was so, that was so
That was so
Yesterday
That was so, oh-oh-oh

[Outro]
Never going back
No, I'm never
Never going back
No, no, I'm never
Never going back
No, I'm never
Never going back
That was so
