The Forgotten Art of Memory Loss

I've got one job,
I'm priceless to you,
You never give a seconds thought before you do,
No-one has seen I'm a castaway,
One moments madness and you've thrown it all away

Stop Talking Now!
Stop Talking Now!
(Thrown it all away)
Stop Talking Now!

I feel so lost,
I can't explain how,
There'd be no surprise if i had been replaced by now,
My time is up I'm here to stay,
Just don't forget that you have thrown it all away
