What's the saddest music video ever ?

[Floogal]

I've always thought the song Happier by Marshmallo and Bastille was quite upbeat and fun when hearing it on the radio. The other day when watching music videos on YouTube it came up. So heartbreaking. A lonely isolated girl is given a puppy by her dad. The girl and the dog become close. Gradually the dog ages and becomes sick until it is put down. The most upsetting thing in the video is the girl sobbing at the vets while the dog puts the paw in her hand to cheer her up.
Thankfully the video has a happy ending, which I won't spoil. But check it out.
What music videos do you find sad?

Kate bush: This woman’s work

Earth Song by Michael Jackson.

Daft Punk - Da Funk

Nothing Compares To You by Sinead OConnor

Concrete angel by Martina McBride

Runaway Train by Soul Asylum, features real life missing people, some of whom have since been found dead and some still missing

Lullaby by Nickelback

Wrong Side of Heaven by FFDP always gets me.

I also shed a little tear whenever I see the Pipes of Peace video.

Second for Runaway train. Very sad

The Suburbs - Arcade Fire

Hurt, Johnny Cash.

And another vote for Runaway Train.

Dancing with tears on my eyes by Ultravox . Shows end of the world by atomic bomb

Khruangbin - So We Won’t Forget. The video had me crying.

Take me to church by hozier, as thats exactly what happens to a lot of people.

I was going to say Hurt by Johnny Cash too

Luca Suzanne Vega

When your gone - Avril Lavigne . Video always made me cry

The Scientist - Coldplay

Yep

I'm Not The Only One by Sam Smith. I find the song beautiful and Diana Agron is impossibly sad in the video.

The ones I was going to say have already been mentioned but definitely Johnny Cash’s cover of Hurt. Him surrounded by the broken remnants of past glories and especially photos of June who had recently died and Sinnead O Connor with the tear running down her beautiful face in Nothing Compares to You (also a cover in fact)

Bronski Beat’s ‘Smalltown Boy’.

Can't watch Johnny cash hurt without a lump in my throat

Monsters - James Blunt

These are the days of our lives, Queen. Freddie Mercury was dying and it's just so very sad.
