Simplicity is key in the emotional video for the Christina Aguilera x A Great Big World duet 'Say Something.'

Xtina, looking gorgeous in a black slip dress and her hair slicked back, sings and cries. The boys of AGBW play piano and sing, and look lost in thought.

The performance footage is spliced with powerful and emotional images of an old man crawling into a hospital bed with his wife as she passes away -- grab a tissue.

There's also a scene of little girl hiding under bed with her dog. Then there is a couple that is breaking up and disentangling themselves. These scenes are woven throughout and they capture the difficult of life and the sometimes fleeting and otherwise enduring nature of human connections.

The song is heavy and the video matches the intensity.
