What song became heartbreaking

What song became heartbreaking once you learned the context behind its origin?

The Eric Clapton one ....Tears from heaven I think it's called and it's after his son died.

Dancing in the Moonlight. One of my favorite songs, very sad, unexpected origin. The song writer and his girlfriend were on vacation at the beach when he was brutally beaten and his gf r*ped by gang members. He wrote the song afterwards, envisioning an idyllic world where everyone is happy and just dances all the time.

Europapa It's all so upbeat and fun and then bam it all burns cause his parents died when he was a kid.

Fictional, but the video tells the story

"I'm Not Gonna Miss You" by Glen Campbell. It's about the singer's Alzheimer's diagnosis.
