I've got 3 that reduce me to tears everytime I hear them...
Daniel (Elton John)
Seasons in the sun (Terry Jacks)
Chasing Cars (Coldplay)
@@JamesandJon33 I suspect your tears for Chasing Cars are the same as mine. I hear the song and get an image in my mind of Grey's Anatomy.
Denny (Jeffrey Dean Morgan) has just died, Izzie (Katherine Heigl) has just got dressed up for Richard's niece's prom, and is lying on the bed with him. The rest of her group of friends (Meredith, Alex, Christina, George and Callie) are there. Alex tells her that Denny isn't Denny anymore, and lifts her off the bed and sits with her in his arms, all whilst we hear an adapted version of Chasing Cars.
Even typing this has brought me to tears.
