I just listened to Cosmic Love by Florence and the Machine, and I remember they played it in Coronation Street when Aidan Connor took his own life. I know it's just a soap but it was heartbreaking and a 23 year old girl from my local area took her own life earlier this year, it just made me think of her.
There are other songs which have the same effect, interested to hear about any other songs that have this effect on people!
