My mother died after spending a long period in an Alzheimer's home. This song accurately portrays the change from somebody we once knew into somebody who is totally removed from us in mind, but not in body.

You should post the words. They are a little bit hard to understand.. I had to listen multiple times to catch them.

IMO, There is a market for this song. It has high identification factor and strong emotional appeal.
You can train a dog to jump through a hoop by positive reinforcement. But if you kick him just once after he jumps through the hoop, he will probably avoid the hoop from then on. The same principle is true of song writing.
