Glee Girls: Ah ah ah ah ah ah ah ah ah ah ah ah ah ah ah ah
Santana: You know the bed feels warmer, sleeping here alone.
You know I dream in colour, and do the things I want.
Brittany: You think you got the best of me, think you had the last laugh, but you think that everything good is gone.
Think you left me broken down, think that I'd come running back.
Baby you don't know me cause your damn wrong!
Glee Girls: What doesn't kill you makes you stronger, stand a little taller.
Doesn't mean I'm lonely when I'm alone.
What doesn't kill you make a fighter, footsteps even lighter.
Doesn't mean I'm over cause you're gone.
What doesn't kill you make you stronger, stronger, just me, myself,and I.
What doesn't kill you make you stronger, stand a little taller.
Doesn't mean I'm lonely when I'm alone.
(Other girls in background: Ah!)
Mercedes: Thanks to you I'm not that broken hearted!
Santana: Thanks to you I'm finally thinking 'bout me.
Santana + Mercedes: You know in the end that day I left was the beginning.
Santana: In the end!
Glee Girls: What doesn't kill you makes you stronger, stand a little taller.
Doesn't mean I'm lonely when I'm alone.
What doesn't kill you makes a fighter, footsteps even lighter.
Doesn't mean I'm over cause you're gone.
What doesn't kill you makes you stronger, stronger, just me myself, and I.
What doesn't kill you makes you stronger.
