Already posted in the match thread, but will repost here. Song about tragic endings, starting again even though it will end bad again because you have belief that it will be different this time, and that's the point.
You'd say I'm putting you on
But it's no joke
It's doing me harm
You know I can't sleep
I can't stop my brain
You know it's three weeks
I'm going insane
You know I'd give you everything I've got for a little peace of mind
