Luna_talia got that one too. It was Some of it by Eric church. The next song is by one of the other artists I saw at the festival,

I'm sorry
But I'm just a girl not usually the kind to show my heart to the world
I'm pretty good at keeping it together
I hold my composure for worse or for better
So I apologize
If you don't like what you see
But sometimes my emotions get the best of me
And falling apart is as human as it gets
You can't hide it, you can't fight what the truth is

You can pretty lie
And say it's okay
You can pretty smile
And just walk away
Pretty much fake your way through anything
But you can't ___ ______
Oh no, you can't dress it up in lace or rhinestones
Don't matter if you're in a crowd or home all alone
Yeah, it's all the same when you're looking in the mirror
A picture of pain
So let it flow like a river

You can pretty lie
And say it's okay
You can pretty smile
And just walk away
Pretty much fake your way through anything
But you can't ___ ______
