Contextual Analysis of "all before" in Lyrics

start

heard it all before

here i will lay my guilt and shame. i leave it all at the cross

all before you

well if these things make your day

seen it all before. in a time these things will change

and i can't be sure if you're something i'd miss

i've heard it all before

so many times. i've

i've heard it! i've. i lived it all before

if you're something I'd miss

I've heard it all before
