(Look whatcha' done, look whatcha' done) And now they're playing our favorite song that We used to dance to, nights like tonight The paint is fadin', feels so amazin' To know you hurt me for the last time So I ain't crying anymore I'm stronger than I was before You keep calling me again But I keep dancing anyway 'Cause now that you're gone, I'm number one Boy, I should thank you for who I've become Don't need no one, this girl's having fun Watch me catch fire, yeah look what you've done Look what you've done Look what you've done The beat pulls my body next to somebody Ain't no more tears now, I'm lost in time Can't take your eyes off, this new life that I've got Boy, I should thank you 'cause this helped me shine So I ain't crying anymore I'm stronger than I was before But you keep calling me again But I keep dancing anyway 'Cause now that you're gone, I'm number one Boy, I should thank you for who I've become Don't need no one, this girl's having fun Watch me catch fire, yeah look what you've done Look what you've done (Look whatcha' done, look whatcha' done) Look what you've done Look what you've done (Look whatcha' done, look whatcha' done) Look what you've done (Look whatcha' done) Baby, can't you see What you've done to me? Look what I've become Look what you have done Look what you have done 'Cause now that you're gone, I'm number one Boy, I should thank you for who I've become (Who I've become) Don't need no one, this girl's having fun Watch me catch fire, yeah look what you've done Look what you've done (Look whatcha' done, look whatcha' done) Look what you've done Look what you've done (Look whatcha' done, look whatcha' done) Look what you've done (Look whatcha' done)
